What they found
Generated two transgene-free iPSC lines from a DFNB9 patient with compound heterozygous OTOF mutations (c.2122C>T and c.5197G>A) and a heterozygous carrier relative. Both lines showed normal pluripotency, karyotype, and trilineage differentiation. The carrier line enables comparative analysis of heterozygous mutation effects on auditory pathology.
How this applies to mini-STRC
Establishes a disease modeling platform for another autosomal recessive hearing loss gene (OTOF/DFNB9) that parallels our STRC/DFNB16 work. The iPSC-derived approach for mechanistic studies and gene therapy optimization is directly transferable — similar compound heterozygous patient lines could be generated for STRC mutations to test mini-STRC constructs in human-derived cells. The carrier line concept is particularly useful for dose-response studies of partial gene function.
Key numbers
- Patient mutations: c.2122C>T and c.5197G>A (compound heterozygous)
- Method: transgene-free episomal reprogramming
