Abstract

Rubinstein-Taybi syndrome (RSTS) is a neurodevelopmental disorder characterized by growth retardation, skeletal anomalies and intellectual disability, caused by heterozygous mutations in either CREBBP (RSTS1) or EP300 (RSTS2) genes. We characterized 3 iPSC lines generated by Sendai from blood of RSTS1 patients with unique non sense c.4435G > T, p.(Gly1479*), c.3474G > A, p.(Trp1158*) and missense c.4627G > T, p.(Asp1543Tyr) CREBBP mutations. All lines displayed iPSC morphology, pluripotency markers, trilineage differentiation potential, stable karyotype and specific mutations. Western-blot using a CREB-Binding Protein N-terminus antibody demonstrated the same amount of full length protein as control in the missense mutation line and reduced amount in lines with stop mutations.
