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.
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

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
