RESUMEN

Objective@#To summarize the clinical characteristics and identify gene mutations of 2 probands with Rubinstein-Taybi syndrome (RSTS).@*Methods@#Clinical characteristics of 2 probands with Rubinstein-Taybi syndrome were summarized. Genomic DNA was extracted from peripheral blood samples from the patients and their parents. Genomic DNA was subjected to whole exome next generation sequencing. Suspected variants were confirmed by Sanger sequencing.@*Results@#The two patients were characterized by typical facial features, broad thumbs and big toes, intellectual disability, and postnatal growth retardation. Two variants of the CREBBP gene, namely c. 3779+ 1G>A and c. 5052_c.5053insT, were respectively identified in the 2 patients. Among these, c. 3779+ 1G>A was a previously known pathological mutation, while c. 5052_c.5053insT was unreported previously. Both variants were predicted to be pathological.@*Conclusion@#Two cases of Rubinstein-Taybi syndrome were diagnosed, which facilitated the diagnosis and genetic counselling.
