Genes affected
POU4F3 (HGNC:9220): (POU class 4 homeobox 3) This gene encodes a member of the POU-domain family of transcription factors. POU-domain proteins have been observed to play important roles in control of cell identity in several systems. This protein is found in the retina and may play a role in determining or maintaining the identities of a small subset of visual system neurons. Defects in this gene are the cause of non-syndromic sensorineural deafness autosomal dominant type 15. [provided by RefSeq, Mar 2009]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Mar 25, 2023 | This variant is not present in population databases (gnomAD no frequency). For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects POU4F3 function (PMID: 18228599). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt POU4F3 protein function. ClinVar contains an entry for this variant (Variation ID: 7080). This missense change has been observed in individual(s) with autosomal dominant deafness (PMID: 18228599, 19462854; Invitae). It has also been observed to segregate with disease in related individuals. This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 223 of the POU4F3 protein (p.Leu223Pro). - |
