Rubinstein-Taybi Syndrome (RTS) is a rare genetic disease that is characterized by various physical anomalies, developmental delay and intellectual disability. It was first described in 1963 by doctors Jack Rubinstein and Hooshang Taybi. The prevalence of this syndrome is estimated to be approximately 1 in every 100,000 live births. Despite its low incidence, it is important to understand its causes, symptoms and treatment options.
Causes of Rubinstein-Taybi Syndrome
RTS is caused by genetic mutations in the CREBBP (cAMP Response Element Binding Protein-Binding Protein) gene in approximately 50-60% of cases, and in the EP300 (E1A Binding Protein P300) gene in approximately 10-15 % of the cases. These genes encode proteins that play important roles in the control of cell growth, the cell cycle, and cell differentiation.
Mutations in the CREBBP and EP300 genes prevent the proteins from properly carrying out their functions, resulting in in the appearance of the characteristic symptoms of RTS. In around 30-40% of cases, the cause of the disease is unknown, which suggests the possibility of the existence of other genes involved in the syndrome.
Symptoms of Rubinstein-Taybi Syndrome
Physical Anomalies
Patients with SRT present a series of physical abnormalities that are characteristic of the disease. Some of the most common include:
- Peculiar facies: distinctive facial features such as wide forehead and eyes, bulbous nose, small mouth, and small jaw
- Microcephaly: abnormally small size of head
- Short stature
- Polydactyly: presence of extra fingers and/or toes
- Skeletal anomalies: such as scoliosis, kyphosis and hip dislocation

Developmental Delay and Intellectual Disability
Children with SRT often experience delayed motor and language development. Additionally, intellectual disability is a common feature of the syndrome, with IQ in the range of mild to moderate disability.
It is important to note that the symptoms of RTS can vary in severity from one patient to another, even among members of the same family affected by the syndrome.
Diagnosis of Rubinstein-Taybi Syndrome
The diagnosis of RTS is based on the clinical evaluation of physical and developmental symptoms. of the patient. Additionally, genetic testing is often performed to identify possible mutations in the CREBBP and EP300 genes. These tests can confirm the diagnosis in cases where the clinical presentation is inconclusive.
It is important that the diagnosis be made by a medical team experienced in the evaluation and treatment of genetic diseases, as this can influence treatment options and in the management of symptoms associated with RTS.
Treatment of Rubinstein-Taybi Syndrome
Currently, there is no specific treatment for RTS, since it is a genetic disease. However, the therapeutic approach focuses on the management of symptoms and the implementation of interventions that can improve the quality of life of patients.
Early Intervention
Early intervention It is essential in the management of children with SRT, as it can help improve their motor, language, and social development. This may include physical, occupational, and speech therapies, as well as specialized educational programs tailored to each child's individual needs.
Multidisciplinary Medical Follow-up
It is recommended that SRT patients be closely followed by a multidisciplinary medical team that includes paediatricians, geneticists, neurologists, therapists and other specialists. This comprehensive approach can guarantee adequate symptom management and personalized care according to the needs of each patient.
Treatment of Clinical Manifestations
Depending on the specific clinical manifestations presented by the patient. patient, additional treatments may be necessary. For example, in cases of severe scoliosis, the use of orthopedic corsets or even surgery may be necessary to correct the deformity.
Psychological and Family Support
The emotional and psychological aspect of the patients with SRT and their families should not be overlooked. It is important to provide psychological support and counseling to both patients and their families to help them cope with the challenges of living with this rare disease.
Conclusion
Rubinstein Syndrome -Taybi is a rare genetic disease that can have a significant impact on the lives of patients and their families. Although there is no specific treatment for TRS, a multidisciplinary approach that includes early interventions, specialized medical follow-up, and treatment of clinical manifestations can improve patients' quality of life and help them reach their full potential.
It is essential to continue research and increase awareness of SRT to improve diagnosis, clinical management and support for those affected. With a comprehensive approach and a patient-centered approach, it is possible to offer high-quality care to people with Rubinstein-Taybi Syndrome.
