Generation of induced pluripotent stem cell (iPSC) line from a 39-year-old deaf patient with the A1555G mutation of mitochondrial DNA.

Sensorineural hearing loss (SNHL) is a prevalent form of deafness commonly arising from damage to the cochlear sensory hair cells and degeneration of the spiral ganglion neurons. In this study, Sendai virus was used to generate an induced pluripotent stem cell (iPSC) line from a 39-year-old female patient diagnosed with severe-to-profound, non-syndromic SNHL. The patient also carries a A1555G mutation in the mitochondrial 12S ribosome RNA gene (MTRNR1). This iPSC line was verified to express pluripotent markers, possess normal karyotype, harbor the specific mutation and demonstrated the capacity to differentiate into three germ layers.
