Genes affected

HTRA2 (HGNC:14348): (HtrA serine peptidase 2) This gene encodes a serine protease. The protein has been localized in the endoplasmic reticulum and interacts with an alternatively spliced form of mitogen-activated protein kinase 14. The protein has also been localized to the mitochondria with release to the cytosol following apoptotic stimulus. The protein is thought to induce apoptosis by binding the apoptosis inhibitory protein baculoviral IAP repeat-containing 4. Nuclear localization of this protein has also been observed. Alternate splicing of this gene results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2016]

This sequence change replaces glycine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 21 of the HTRA2 protein (p.Gly21Ala). This variant is present in population databases (rs768870295, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with HTRA2-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. -
