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.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.014722139).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000269 (41/152258) while in subpopulation AFR AF= 0.000842 (35/41558). AF 95% confidence interval is 0.000622. There are 0 homozygotes in gnomad4. There are 23 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces serine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 139 of the HTRA1 protein (p.Ser139Ala). This variant is present in population databases (rs530087850, gnomAD 0.1%). This missense change has been observed in individual(s) with clinical features of Cerebral arteriopathy with subcortical infarcts and leukoencephalopathy (PMID: 25929831). ClinVar contains an entry for this variant (Variation ID: 447571). 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 not expected to disrupt HTRA1 protein function. 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. -
