Derivation of iPSC line UMi029-A bearing a hearing-loss associated variant in the SMPX gene.

Hereditary hearing loss (HL) is the most common sensory disorder with multiple potential modes of inheritance, such as X-linked. Multiple loci have been associated with X-linked HL, including variants in the Small Muscle Protein X-Linked (SMPX) gene responsible for deafness, X-linked 4 (DFNX4) (OMIM 300066). Here we describe the derivation of an induced pluripotent stem cell (iPSC) line from an individual bearing a novel splice variant (c.133-1 G > A) that leads to a frameshift creating a premature stop codon (p.(Gly45Val*36)) in SMPX[1].
