Reprogramming Of Human Peripheral Blood Mononuclear Cell (Pbmc) From A Patient Suffering From Hearing Loss Into Ipsc Line (Sdqlchi035-A) Maintaining Compound Heterozygous Variations In Gjb2 Gene

Mutation in the gap junction beta-2 (GJB2) gene is a main cause of autosomal-recessive nonsyndromic hearing loss (ARNSHL). The c.235delC and c.299-300del mutations are more common mutations in Chinese Han deaf patients, in which the compound heterozygous mutations of these two sites cause severe-toprofound hearing loss in a significant percentage. We established an induced pluripotent stem cell (iPSC) line from a 2-year-old boy with hearing loss, caused by compound heterozygous mutations in GJB2 (c.235delC and c.299-300del). The iPSCs was verified based on pluripotency markers and demonstrated trilineage differentiation potential in vitro.
