Genes affected
PAX4 (HGNC:8618): (paired box 4) This gene is a member of the paired box (PAX) family of transcription factors. Members of this gene family typically contain a paired box domain, an octapeptide, and a paired-type homeodomain. These genes play critical roles during fetal development and cancer growth. The paired box 4 gene is involved in pancreatic islet development and mouse studies have demonstrated a role for this gene in differentiation of insulin-producing beta cells.

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 121 of the PAX4 protein (p.Arg121Trp). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with clinical features of type 1 or type 2 diabetes as well as in non-diabetic controls (PMID: 11723072, 16423628, 31264968, 33031055). ClinVar contains an entry for this variant (Variation ID: 13790). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). Experimental studies have shown that this missense change affects PAX4 function (PMID: 15596543, 27334367). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
