Abstract
PURPOSE
A case report of a six-year and five-month-old female admitted with typical symptoms of Rubinstein-Taybi syndrome is presented. Clinical and rehabilitation settings where she acquired her reading, writing, and communication skills are described.
METHODS
Because of her cognitive disabilities, a multidisciplinary and long-term intervention (2014–2020) was necessary. Treatment included orthoptic, psychomotor, logopedic, occupational, and neuropsychological care. Her family and school were involved.
RESULTS
Increased attention led to decreased dysfunctional behaviors. Test results are still below average, but there has been significant improvement. Better communication skills resulted from increased phonetic range, improved articulation, lexical-semantic structure, comprehension, and production of sentences. Digital technologies played a significant role in enhancing her communication skills, not just in social interactions but also in school activities. The patient is oriented in time and space with the help of agendas and calendars. She can express her needs and compose concise narratives. As a result of acquiring functional skills, she is better equipped to handle real-life situations, which has led to increased social and family activities.
CONCLUSION
This case report highlights the importance of personalized rehabilitation programs. Obtaining an early genetic diagnosis is crucial for timely tailored rehabilitation, and any delays in this process can hinder progress.

Introduction
Rubinstein-Taybi syndrome (RTS) is a rare genetic disease [1] This syndrome usually occurs sporadically. Most cases are attributable to de novo mutations [2–4]. However, it can also be inherited as an autosomal dominant disorder [5].
Physical features include microcephaly, characteristic facial appearance, broad thumbs/halluces, and post-natal growth retardation. Behavioral and cognitive characteristics associated with RTS include impulsivity, repetitive behaviors, moderate to severe intellectual disability, and delayed speech [6]. The estimated prevalence at birth is about one in 100,000–125,000 live births [5, 7]. During infancy, individuals with RTS can establish good social relationships; in adulthood, sudden mood changes and obsessive-compulsive behavior can occur.
In 50–60% of cases, the syndrome is linked to mutations in cyclic-AMP-response element binding protein (CREB)-binding protein gene (CREBBP) localized at 16p13.3 [2–4, 8–10]. In 8–10% of cases, RTS is caused by a mutation of chromosome 22q13 encoding for E1-A associated protein p300 [4, 9–11]. CREBBP (RST1) and EP300 (RST2) genes express homologous proteins belonging to the KAT3 family of lysine acetyltransferases and play different roles in motor skill learning as transcriptional coactivators. The spectrum of CREBBP mutations includes point mutations (30–50% ) [2, 3, 8, 9] and deletions (10% ). In EP300, the genetic defects include 21-point mutations and five deletions [9, 11]. Finally, 30% of cases are caused by unknown genetic variations [12].
This case describes a female with RTS who underwent a multidisciplinary intervention to take care of her disabilities globally and promote her autonomy, functioning, and social integration in daily life. The study was conducted according to the World Medical Association Declaration of Helsinki. The Institutional Review Board of KOS-CARE approved the study, with approval number N.03, February 10, 2022. Written informed consent for publication was obtained from the family.
Case report
The child is the second of three children, none of whom had phenotypic similarities with the patient. She was born at term (41st week) by partus caesareus after a normal pregnancy, weighing 3 kg 575 g. At age three, she underwent a right lachrymal duct stenosis correction [13, 14]. She had a history of recurrent respiratory infections, an episode of pyelonephritis, growth delay, coloboma on the optic nerve of the right eye [15], and patent ductus arteriosus with a slight-moderate left-right shunt [16], which was closed at the age of six; no major cardiopathy was reported.
At six years and five months, she was admitted after undergoing rehabilitation, mainly language-focused, at another hospital. Clinical assessment revealed the smile characteristic of RTS, with a partial closure of the eyes, ogival palate [17], short fingers, broad thumbs, bilateral flat feet with overlapping of the second toe of the left foot, bilateral deviation of the fifth toe, initial structural scoliosis (Fig. 1), reduced eye-hand coordination, and autonomous pathway. No history of epileptic seizures nor pharmacological therapy was reported.

Clinical findings of the patient. In the figure are represented the pictures of distinctive physical features, namely angled and broad thumbs (left, right), bilateral flat feet with overlapping of the second toe of the left foot and bilateral deviation of the fifth toe (left, bottom), and initial structural scoliosis (right). Permission was obtained from the parents for the use of the photographs.
Beyond delayed cognitive development, the child exhibited a language disorder characterized by reduced comprehension and simplified speech. She also had orofacial praxic difficulties and accentuated attention and memory fluctuations. Although social, she faced communication difficulties, necessitating an additional year of kindergarten to address her cognitive and linguistic delays. The child displayed poor coordination, struggling with object manipulation and daily activities when performed without adult assistance.
RTS was first suspected on clinical grounds at age three. Genetic testing for deletions in the region of the CREBBP gene [18] by fluorescence in situ hybridization in metaphase chromosomes from lymphocytes did not show deletions in either chromosome 16. The same technique extended to the region containing the EP300 gene did not show deletions in either chromosome 22. At age four years and three months, the diagnosis of RTS was confirmed by the multiplex ligation-dependent probe amplification technique (MRC Holland kit, Amsterdam, Netherlands), more sensitive than the standard method (denaturing high-performance liquid chromatography and direct sequencing) for detecting exonic deletions/duplications in CREBBP in genomic DNA extracted from peripheral blood. A variation was found in exon one of CREBBP. This variation is not reported in the literature or the Leiden Open Variation Database. The deletion was confirmed by independent analysis using the comparative genomic hybridization technique.
Gross motor development was evaluated using the Gross Motor Function Classification System [19]. Functional sitting was measured by the Level of Sitting Scale [20]. Finally, walking was assessed using the Six-Minute Walk Test [21].
An ophthalmologic exam was performed to measure visual acuity and oculomotor function.
Language was assessed using standardized tests, selected based on the patient’s developmental level. Test di Valutazione del Linguaggio a (TVL) [22] was used to measure denomination, word/sentence comprehension, and sentence repetition (metaphonological skills - Valutazione delle Competenze Metafonologiche) test [23]. Since her age exceeded the normative data of TVL (six years), the raw score was converted into the “age test” score for scoring purposes. Naming, lexical, and grammatical comprehension, as well as word/non-word and sentence repetition were evaluated using the Batteria per la Valutazione del Linguaggio b (4–12) [24]. Reading ability and comprehension were assessed with Prove di Lettura MT2 and MT3 tests [25, 26]. Writing ability was measured with the Batteria per la Valutazione della Dislessia e della Disortografia Evolutiva-2 c , [27], while dictation was measured with the Batteria per la Valutazione della Scrittura e delle Competenze Ortografiche d [28].
A neuropsychological assessment was conducted using age-standardized tests and semi-structured observations. Cognitive development was assessed with the Wechsler Preschool and Primary Scale of Intelligence-III [29] and Wechsler Intelligence Scale for Children-IV (WISC-IV) scales [30]; cognitive domains were evaluated with Batteria di Valutazione Neuropsicologica e (BVN 5-11) [31] and the Batteria di Valutazione Neuropsicologica per l’adolescenza f (BVN 12–18) [32]. Short-term and visual-spatial memories, verbal recall, and phonemic and category fluency were evaluated. The Developmental Test of Visual-Motor Integration (VMI) [33] was used to study visual-motor integration capacity.
The Canadian Occupational Performance Measure (COPM) [34] was administered at age 13 to explore the impact of technologies on the patient’s self-perception of performance and satisfaction with daily living activities.
Goals and intervention
A multidisciplinary intervention was performed, aligning therapeutic goals with the family to improve visuomotor coordination, attention, communication, language, and executive functions. Additional aims included promoting school inclusion and providing family training. Parent sessions focused on emotional support, communication improvement, and stress reduction [35, 36], with guidance on managing dysfunctional behaviors (impulsiveness, distractibility, repeatability). Regarding motor functions, all administered scales showed a ceiling effect, indicating no deficits. As a result, no additional actions were taken.
Due to visual difficulties, the child received immediate optical correction and orthoptic treatment. Ophthalmologic examination revealed low vision in both eyes (corrected visual, 6/10), ptosis in the right upper eyelid, an oculomotor disorder characterized by intermittent exotropia, bilateral deficits in elevation and depression, hyperfunction of small oblique muscles, abduction deficit of the right eye, and an anomalous hyperextended head position. An accommodation target was utilized to address these issues, along with presenting objects systematically to stimulate pursuit and saccadic eye movements, improving attention and location scanning accuracy [37]. Surgery in September 2015 partially corrected the strabismus.
Eye-hand coordination exercises involving horizontal and vertical lines were recommended to practice right-left laterality movements and wrist flexion/extension.
Speech therapy aimed to enhance communication, focusing on lexical-semantic structure, comprehension, morphosyntactic production, and overall communicative effectiveness. Stereognosis with physical shapes (Fig. 2) was used to promote learning alphabet letters.

Facilitation for learning to write the letter “A”. The child was asked to follow a sinusoidal track, staying within the path (black lines) without touching the two edges (left). Since she had difficulty recognizing and learning abstract shapes (letters or geometric figures), stereognosis recognition of shapes was employed, using tangible forms, such as the tree crown (middle) or the roof of a house (right).
Capital letters on double-lined paper were used as well (Fig. 3).

Correct holding of pencil and facilitation for writing letters on lined paper. An adaptive device facilitated a proper grip of the writing instrument, resulting in legible writing. Following a prolonged period of gradual learning, she has demonstrated the capability of producing uppercase block letters on a spacious, lined paper featuring double-line spacing.
The syllabic method was applied for reading and writing [38].
Cognitive abilities were developed using the Feuerstein method of Instrumental Enrichment (IE), initially basic [39], then the standard IE [40].
Psychomotor treatment aimed to enhance motor skills and spatial awareness through exercises targeting personal, peripersonal, and extrapersonal space. Fine and praxic movements were practiced with selective reinforcement for the right hand.
Activities included time-space orientation tasks like writing the date and sequencing daily activities.
Occupational therapy incorporated digital technologies, like smartphones and computers, to teach her internet browsing (Google Chrome; YouTube), the use of word-processing software (OOo4Kids, version 1.3; Microsoft Office Suite), and text messaging.
The patient’s language skills were monitored longitudinally, revealing consistent improvement despite scores on each test remaining below normative data. Notably, improvements were observed in orofacial apraxia [41], reading, word/sentence comprehension, and naming [42], as detailed in Tables 1 and 2.

Currently, she can compose simple essays through self-dictation and write individual words in printed capitals, albeit with minor orthographic errors resembling those of native Italian speakers with aphasia [43]. She makes errors when reading short, simple, and printed texts in capitals. Rereading with a ruler reduces the risk of missing a line and improves decoding accuracy.
Regarding cognitive assessment (Table 3), processing speed subtests of the WISC-IV [30] scale were not administered because of her hand-eye coordination difficulties. The General Ability Index (GAI) was calculated, and her score was below average, falling in the range of moderate intellectual disability according to the Diagnostic and Statistical Manual of Mental Disorders criteria [44, 45].

Scores on BVN 5-11 [31] and BVN 12–18 [32] showed that her visual-spatial memory span remained constant. The ability to learn unstructured verbal material and delayed recall of items remained poor. However, improvements were seen in internal lexical access. Visual-motor integration capabilities, as tested by VMI, remained reduced across all collections.
The Draw-a-Person test [46–48] showed progress. In the last administration, the child could draw a human figure with all the elements and details in the correct positions (Fig. 4).

Progress in drawing the human figure. In the most recent version (age 13), some progress was noticed compared to the previous performance. Indeed, the human figure was recognized, the drawing was well-placed on the page, details such as the face with eyes, mouth, and hair were depicted, and the trunk was elongated with correctly placed legs and arms. The drawing matched a mental age of five years.
Although formal measures assessing inattention and/or impulsivity were not used in this study, clinical observations revealed improvements in focused and sustained attention, with a partial reduction of impulsive behaviors. Note that no medications were administered.
Finally, the scores on the COPM scale (Table 4) demonstrated a significant increase in both self-perception of her performance and degree of satisfaction, meaning that the treatment was effective.

The child identified the most important problems and ranked them in order of importance: listening to music (importance rate, 9), texting (importance rate, 8), browsing the internet (importance rate, 8), and composing narratives (importance rate, 7). For each problem, she rated it based on performance and satisfaction. The average score was calculated by adding together the performance and satisfaction scores for all problems (total score) and dividing by the number of problems. The assessment (T1) and reassessment (T2) were performed at the beginning and end of treatment, respectively. The treatment is considered effective if the change in performance and/or satisfaction is greater than two (Performance Average Score T2 – Performance Average Score T1, Satisfaction Average Score T2 – Satisfaction Average Score T1).
The case describes a girl with RTS, which is known to cause behavioral and neuropsychiatric issues. However, there is a lack of data about its natural progression [49]. Age-related changes have been described in RTS with mood difficulties, and temper tantrums may increase with age [50]. The pathogenic variant can affect behavioral, cognitive, and emotional characteristics [51]. No RTS-specific interventions or treatments exist [49]; diagnostic criteria and care practices are heterogeneous worldwide [52]. However, international recommendations for clinical diagnostic criteria, molecular investigations, long-term management of physical and behavioral issues, and care planning for different types of RTS are now available [52]. To date, therapies directed toward speech, behavior, and daily living skills, like the one presented, have proven crucial [49]. It has been demonstrated that early speech and language therapy is beneficial in supporting the development of communication and subsequently reducing challenging behaviors, which leads to a better quality of life [50].
In this instance, due to her severe intellectual disability, a multidisciplinary approach was necessary to improve the patient’s reading, writing, and daily life skills.
Addressing the previously neglected visual difficulties was crucial in enabling the child to perform optimally and achieve the goals set by the speech and psychomotor therapists. Collaborating with a team of specialists across different settings improved her ability to stay engaged in the same task for longer periods of time. This resulted in a reduction of the most regressive and dysfunctional aspects of her behavior [53]. Family involvement from the early phases and a continuous dialogue with teachers were crucial too.
While test results did not demonstrate improvements, her social and conversational skills have progressed notably. She actively engages in conversations, poses questions, and articulates her interests and needs. She can independently express her requests and share personal accounts using reading and writing for orientation, enhancing her autonomy in familiar environments [54].
Furthermore, her communication abilities and social interactions have been enhanced through the utilization of computers and smartphones. These technologies have not only facilitated educational accessibility but also fostered increased engagement in school activities.
Conclusions
A long-term multidisciplinary rehabilitation [55], like the one presented, increased her independence in daily life and enabled the application of acquired functional and communication skills, despite her intellectual disability which affected her test scores.
The cognitive delay associated with these disorders and the limits imposed by the syndrome result in low investment in rehabilitation programs [56]. This issue is further compounded by delays in genetic diagnosis and challenges in tailoring specific rehabilitation programs. However, personalized programs focusing on individual skills are crucial for enhancing autonomy and quality of life [47]. Continuous counseling and support from family, school, and social environments are essential for successful rehabilitation outcomes in patients with complex disabilities.
