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]

Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Nov 04, 2022 | Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge - |
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Feb 21, 2021 | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with POU4F3-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with glutamine at codon 33 of the POU4F3 protein (p.Arg33Gln). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and glutamine. - |
