Genes affected

NDRG1 (HGNC:7679): (N-myc downstream regulated 1) This gene is a member of the N-myc downregulated gene family which belongs to the alpha/beta hydrolase superfamily. The protein encoded by this gene is a cytoplasmic protein involved in stress responses, hormone responses, cell growth, and differentiation. The encoded protein is necessary for p53-mediated caspase activation and apoptosis. Mutations in this gene are a cause of Charcot-Marie-Tooth disease type 4D, and expression of this gene may be a prognostic indicator for several types of cancer. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, May 2012]

This sequence change replaces serine with asparagine at codon 362 of the NDRG1 protein (p.Ser362Asn). The serine residue is weakly conserved and there is a small physicochemical difference between serine and asparagine. This variant is present in population databases (rs749124058, ExAC 0.005%). This variant has not been reported in the literature in individuals affected with NDRG1-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. -
