Generation and characterization of human iPSC line SANi013-A from a Diamond-Blackfan anemia syndrome (DBAS) patient carrying a heterozygous RPS26 c.95-98 duplication variant.

Diamond-Blackfan Anemia Syndrome (DBAS) is a rare inherited bone marrow failure syndrome diagnosed in early childhood, marked by hypoplastic anemia, congenital anomalies, and increased cancer risk. Most cases involve loss-of-function mutations in ribosomal protein genes, disrupting ribosome biogenesis. We generated iPSC line SANi013-A from a patient with a de novo heterozygous RPS26 c.95-98 duplication. Proerythroblasts derived from peripheral blood were reprogrammed using a non-integrating Sendai virus method. The iPSC line SANi013-A displayed a normal karyotype, expressed pluripotency markers, and differentiated into all three germ layers. This line offers a valuable model for studying DBAS pathogenesis, especially erythropoietic defects.
