ICD10 code of Rubinstein-Taybi Syndrome and ICD9 code

Rubinstein-Taybi Syndrome is officially classified under ICD-10 code Q87.81 (Other specified congenital malformation syndromes, predominantly affecting facial appearance) and was historically categorized under ICD-9 code 759.89. These diagnostic codes are essential for medical billing, clinical record-keeping, and ensuring that patients receive appropriate specialized care within the healthcare system.

What is the clinical significance of Rubinstein-Taybi Syndrome?

Rubinstein-Taybi Syndrome (RSTS) is a rare genetic disorder characterized by short stature, moderate-to-severe intellectual disability, distinctive facial features, and broad thumbs and halluces (big toes). Clinicians often identify Rubinstein-Taybi Syndrome during infancy or childhood due to these characteristic physical markers. Because it is a multisystem condition, patients with Rubinstein-Taybi Syndrome often require a coordinated multidisciplinary team, including geneticists, pediatricians, and specialized therapists to manage the complex health challenges associated with the syndrome.

How is a diagnosis of Rubinstein-Taybi Syndrome confirmed?

Diagnosis of Rubinstein-Taybi Syndrome is typically suspected based on clinical presentation and confirmed through molecular genetic testing. Most cases are caused by mutations or deletions in the CREBBP gene (approximately 50-60%) or the EP300 gene (approximately 3-8%). Genetic counselors play a vital role in interpreting these results for families. Currently, 232 people with Rubinstein-Taybi Syndrome have joined the DiseaseMaps.org community, providing a unique network for families seeking peer support and shared clinical experiences.

What are the common medical features associated with this condition?

While every individual's experience with Rubinstein-Taybi Syndrome is unique, clinical literature identifies several recurring health concerns that practitioners monitor closely:

• Skeletal anomalies: Specifically broad and often angulated thumbs and big toes, which are hallmark diagnostic features.


• Growth and Development: Significant delay in developmental milestones and postnatal growth deficiency.


• Facial Characteristics: Downward-slanting palpebral fissures, a high-arched palate, and a "beaked" nose.


• Medical Comorbidities: Increased risk for cardiac defects, renal abnormalities, and a predisposition to benign or malignant tumors.


• Behavioral Profile: Many individuals exhibit a friendly and sociable personality, though challenges with attention span and sensory processing are common.

Is Rubinstein-Taybi Syndrome hereditary?

In the vast majority of cases, Rubinstein-Taybi Syndrome occurs sporadically due to a de novo (new) mutation in the affected individual, meaning it is not inherited from the parents. The recurrence risk for siblings of a child with Rubinstein-Taybi Syndrome is generally very low (less than 1%), though professional genetic counseling is always recommended to assess the specific family context and confirm whether a parental germline mosaicism might be present.

Next steps

• Consult with a clinical geneticist to verify molecular diagnosis and discuss family planning.


• Schedule routine screenings with a cardiologist, ophthalmologist, and dentist, as these specialists are vital for managing Rubinstein-Taybi Syndrome.


• Connect with the 232 members on DiseaseMaps.org to share resources and coping strategies for daily management.


• Reach out to organizations like the Rubinstein-Taybi Syndrome Support Group for educational materials and advocacy updates.
