Summary: 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]

In this study, we identified a novel hemizygous variant, c.870G > T in the POU3F4 gene, leading to a substitution of a Lysine with an Asparagine in position 290, in two brothers from one Italian family with identical inner ear abnormalities specific to the X-linked deafness-2 (DFNX2, MIM 304400).

POU3F4 mutations can be predicted by incomplete partition type III anomaly by radiological examination of the inner ear. All six of the patients showed mixed hearing loss, but none showed fluctuations in hearing, which may be related to the lack of vestibular aqueduct enlargement at the operculum.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
