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

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0015049279).
• BP6: Variant 10-122461711-C-T is Benign according to our data. Variant chr10-122461711-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 299044.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr10-122461711-C-T is described in Lovd as [Benign]. Variant chr10-122461711-C-T is described in Lovd as [Likely_benign].
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.152 is higher than 0.05.
