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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.14815801).
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0000197 (3/152214) while in subpopulation NFE AF= 0.0000441 (3/68038). AF 95% confidence interval is 0.0000117. There are 0 homozygotes in gnomad4. There are 2 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAdExome4 at 40 AD gene.

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineApr 04, 2014Variant classified as Uncertain Significance - Favor Benign. The Pro135Ser varia nt in POU4F3 has not been previously reported in individuals with hearing loss, but has been identified in 0.02% (2/8598) of European American chromosomes by th e NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs200 286254). Computational prediction tools and conservation analyses suggest that t he Pro135Ser variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, the clinical significan ce of this variant cannot be determined with certainty; however based upon the c omputational data and the presence of the variant in the general population, we would lean towards a more likely benign role. -
