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]

The gene has 1 curated benign missense variants. Trascript score misZ: 0.60352 (below the threshold of 3.09). GenCC associations: The gene is linked to autosomal dominant nonsyndromic hearing loss 15, autosomal dominant nonsyndromic hearing loss, nonsyndromic genetic hearing loss.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.831

BS1

Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0000363 (53/1461892) while in subpopulation NFE AF = 0.0000441 (49/1112010). AF 95% confidence interval is 0.0000337. There are 0 homozygotes in GnomAdExome4. There are 30 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The Cys35Arg variant in the POU4F3 gene has not been reported in individuals wit h hearing loss but has been identified in 0.01% (1/8600) of European American ch romosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EV S/; dbSNPrs147927112). Although this variant has been identified in the general population, its frequency is not high enough to rule out a pathogenic role. Comp utational analyses (biochemical amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) suggest that the Cys35Arg variant may impact the protein, t hough this information is not predictive enough to determine pathogenicity. In summary, additional information is needed to determine the clinical significance of this variant. -
