Genes affected
POU3F4 (HGNC:9217): (POU class 3 homeobox 4) This gene encodes a member of the POU-III class of neural transcription factors. This family member plays a role in inner ear development. The protein is thought to be involved in the mediation of epigenetic signals which induce striatal neuron-precursor differentiation. Mutations in this gene are associated with X chromosome-linked nonsyndromic mixed deafness. [provided by RefSeq, Dec 2012]

The Ser161Arg variant in POU3F4 has not been previously reported in individuals with hearing loss. Data from large population studies are insufficient to assess the frequency of this variant. Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the Ser161Arg variant is uncertain. -
