Genes affected
HTRA1 (HGNC:9476): (HtrA serine peptidase 1) This gene encodes a member of the trypsin family of serine proteases. This protein is a secreted enzyme that is proposed to regulate the availability of insulin-like growth factors (IGFs) by cleaving IGF-binding proteins. It has also been suggested to be a regulator of cell growth. Variations in the promoter region of this gene are the cause of susceptibility to age-related macular degeneration type 7.

Collection Method: clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 295 of the HTRA1 protein (p.Gly295Arg). This variant is present in population databases (rs587776873, gnomAD 0.002%). This missense change has been observed in individuals with autosomal dominant and recessive cerebral arteriopathy with subcortical infarcts and leukoencephalopathy (PMID: 21115960, 28782182; Invitae). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 30244). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt HTRA1 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects HTRA1 function (PMID: 31316458). For these reasons, this variant has been classified as Pathogenic. -
