Generation of iPSC lines and isogenic gene-corrected lines from two individuals with RPS19-mutated Diamond-Blackfan anemia syndrome.

ABSTRACT

Diamond-Blackfan anemia syndrome (DBAS) is an inherited bone marrow failure disorder that typically presents in infancy as hypoplastic anemia and developmental abnormalities in approximately 50% of cases. DBAS is caused by haploinsufficiency in one of 24 ribosomal protein genes, with RPS19 mutations accounting for 25% of cases. We generated iPSC lines from two patients with different heterozygous RPS19 mutations (c.191T > C and c.184C > T) and isogenic lines in which the mutations were corrected by Cas9-mediated homology directed repair.
