Every July 3rd, International Rubinstein-Taybi Syndrome Day (RTS) is commemorated, a date dedicated to raising awareness and educating the global population about this rare condition that affects 1 in every 150,000 births.
The choice of this date is not accidental: it coincides with the anniversary of the passing of Dr. Jack Rubinstein, one of the doctors who identified the disease along with radiologist Hooshang Taybi in 1963.
What is Rubinstein-Taybi Syndrome?
Rubinstein-Taybi Syndrome is a rare disease generally caused by mutations in the CBP or EP300 genes, which play a crucial role in the regulation of gene expression. It is also known as the “Broad Thumb-Hallux Syndrome” due to one of its most distinctive physical characteristics: the first digit of the hands and feet is broad and angulated. This syndrome affects men and women equally, regardless of ethnic background.
Main symptoms
The symptoms of SRT are varied and may include:
Microcephaly: Head smaller than normal.
Particular facial and physical traits: Highly arched eyebrows, wide nasal bridge, pointed nose, and congenital glaucoma, among others.
Short stature: Growth below average.
Dental malformations: Anomalies in the structure and arrangement of the teeth.
Respiratory distress: Problems breathing that may require treatment.
Constipation: Frequent gastrointestinal problems.
Hearing loss: Auditory difficulties that vary in severity.
Psychomotor developmental delay: Motor and cognitive performance slower than average.
Abnormal heartbeats: Irregularities in the heart rhythm.
Slow development of cognitive skills: Slower progress in learning and intellectual abilities.
Diagnosis and treatment
The diagnosis of RTS is performed by a medical specialist through a detailed physical examination to identify characteristic features. In addition, imaging techniques of the hands and feet are used, as well as genetic testing to analyze mutations in the CBP and EP300 genes.
The treatment for Rubinstein-Taybi Syndrome varies according to the complexity of each case and includes:
Surgery: Correction of bone malformations in thumbs and toes.
Therapies: Programs designed to improve psychomotor development.
Medical treatment: Care for heart disorders, hearing loss, and gastroesophageal reflux.
A call to awareness
International Rubinstein-Taybi Syndrome Awareness Day is an opportunity to raise awareness about this rare disease and promote research and support for those affected. Collaboration between healthcare professionals, families, and the community at large is essential to improve the quality of life for those living with this condition.
By better understanding Rubinstein-Taybi Syndrome, we can foster a more inclusive and supportive environment for those who need it, moving toward a future where rare diseases receive the attention and treatment they deserve.
