Genes affected
PAX2 (HGNC:8616): (paired box 2) PAX2 encodes paired box gene 2, one of many human homologues of the Drosophila melanogaster gene prd. The central feature of this transcription factor gene family is the conserved DNA-binding paired box domain. PAX2 is believed to be a target of transcriptional supression by the tumor suppressor gene WT1. Mutations within PAX2 have been shown to result in optic nerve colobomas and renal hypoplasia. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Dec 2014]

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 247 of the PAX2 protein (p.Arg247His). This variant is present in population databases (rs747639879, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with PAX2-related conditions. ClinVar contains an entry for this variant (Variation ID: 534187). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
