Genes affected

NEUROG3 (HGNC:13806): (neurogenin 3) The protein encoded by this gene is a basic helix-loop-helix (bHLH) transcription factor involved in neurogenesis. The encoded protein likely acts as a heterodimer with another bHLH protein. Defects in this gene are a cause of congenital malabsorptive diarrhea 4 (DIAR4).[provided by RefSeq, May 2010]

This sequence change replaces alanine with valine at codon 186 of the NEUROG3 protein (p.Ala186Val). The alanine residue is moderately conserved and there is a small physicochemical difference between alanine and valine. This variant is present in population databases (rs760598444, ExAC 0.007%). This variant has not been reported in the literature in individuals affected with NEUROG3-related conditions. 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 tolerated. 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. -
