Genes affected
PTPRQ (HGNC:9679): (protein tyrosine phosphatase receptor type Q) This locus encodes a member of the type III receptor-like protein-tyrosine phosphatase family. The encoded protein catalyzes the dephosphorylation of phosphotyrosine and phosphatidylinositol and plays roles in cellular proliferation and differentiation. Mutations at this locus have been linked to autosomal recessive deafness. [provided by RefSeq, Mar 2014]

Significance:Uncertain significance
Review Status:criteria provided, single submitter

The M2196V variant in the PTPRQ gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The M2196V variant is observed in 19/9348 (0.2%) alleles from individuals of European background, in the ExAC dataset (Lek et al., 2016). The M2196V variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position where amino acids with similar properties to Methionine are tolerated across species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret M2196V as a variant of uncertain significance.
