Broad thumbs and broad first toes Mental disability Cryptorchidism in males Unusual faces involving the eyes, nose, and palate Anesthesia may be dangerous in these patients: Any situations requiring the administration of anesthesia or succinlycholine e. The protein, called CREB-binding proteinplays an important role in regulating cell growth and division and is essential for normal fetal development.
Pathophysiology[ edit ] The detailed biochemical mechanism that leads to BBS is still unclear.
The gene products encoded by these BBS genes, called BBS proteins, are located in the basal body and cilia of the cell. BBSome is proposed to be responsible for transporting intracellular vesicles to the base of the cilia and to play an important role in the ciliary function.
BBS6 [ citation needed ] Relation to other rare genetic disorders[ edit ] Recent findings in genetic research have suggested that a large number of genetic disordersboth genetic syndromes and genetic diseasesthat were not previously identified in the medical literature as related, may be, in fact, highly related in the genetypical root cause of the widely varying, phenotypically observed disorders.
BBS is one such syndrome that has now been identified to be caused by defects in the cellular ciliary structure. Thus, BBS is a ciliopathy. Laurence—Moon—Biedl—Bardet syndrome is no longer considered as valid terms in that patients of Laurence and Moon had paraplegia but no polydactyly or obesity, which are the key elements of the Bardet—Biedl syndrome.
Laurence—Moon syndrome is usually considered a separate entity. However, some recent research suggests that the two conditions may not be distinct. Archived from the original on Milder variants of Rubinstein-Taybi syndrome have been reported with less retardation and more subtle clinical features.
as many as 5% of patients with Rubinstein-Taybi syndrome have an increased risk of tumors. including medulloblastoma.
concordance rates are very high in monozygotic twins live births. Abstract Objective Rubinstein-Taybi Syndrome is a rare genetic disorder with characteristic features including downward slanting palpebral fissures, broad thumbs and halluces, and mental retardation.
Systemic features may involve cardiac, auditory, ophthalmic, endocrine, nervous, renal and .
PubMed comprises more than 28 million citations for biomedical literature from MEDLINE, life science journals, and online books.

The Shodair genetics team first evaluated Sotara when she was 6 years old . Rubinstein-Taybi Syndrome is also referred to as broad thumb-hallux syndrome or Rubinstein syndrome. Here the symptoms include intellectual disability along with very distinctive facial features.
Such children tend to have broad thumbs and first toes. the RT syndrome and meta-analyze cases. Key Words: Rubinstein-Taybi syndrome, Chromosome 16 p, Mental retardation, CBP gene.
Introduction In Rubinstein and Taybi described a new syndrome characterised by broad thumbs and toes, facial abnormalities and mental re-tardation.
Rubinstein-Taybi syndrome (RTS).
