Generation of three iPSC lines (IAIi002, IAIi004, IAIi003) from Rubinstein-Taybi syndrome 1 patients carrying CREBBP non sense c.4435G>T, p.(Gly1479*) and c.3474G>A, p.(Trp1158*) and missense c.4627G>T, p.(Asp1543Tyr) mutations

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.
