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]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM1: In a DNA_binding_region Homeobox (size 59) in uniprot entity PO3F4_HUMAN there are 16 pathogenic changes around while only 0 benign (100%) in NM_000307.5
• PM4: Nonframeshift variant in NON repetitive region in NM_000307.5. Strenght limited to Supporting due to length of the change: 1aa.
