Rubinstein-Taybi syndrome

Ru·bin·stein-Tay·bi syn·drome

(rū'bĭn-stīn tā'bē),
mental retardation, broad thumb and great toe, antimongoloid slant to the eyes, thin and beaked nose, microcephaly, prominent forehead, low-set ears, high arched palate, and cardiac anomaly; a submicroscopic chromosomal defect may be causative, but evidence suggests that this syndrome is due to mutation in the gene encoding transcriptional coactivator CREB-binding protein on chromosome 16p.


A gene on chromosome 16p13.3 that encodes a ubiquitously expressed protein involved in the transcriptional coactivation of various transcription factors. CREBBP acts as a scaffold to stabilise additional protein interactions with the transcription complex; it has intrinsic histone acetyltransferase activity, and acetylates both histone and non-histone proteins.

Molecular pathology
CREBBP mutations cause Rubinstein-Taybi syndrome (RTS); chromosomal translocations of CREBBP are associated with acute myeloid leukaemia.

She had been desperately ill since being born five weeks prematurely and needed surgery to correct a heart defect caused by a rare genetic condition called Rubinstein-Taybi syndrome. Sarah still finds this painful time very difficult to discuss, but does say that the arrival of Nell has helped the couple open a 'new chapter' in their lives.
