Genes affected

AMZ2 (HGNC:28041): (archaelysin family metallopeptidase 2) The protein encoded by this gene is a zinc metalloprotease that displays some activity against angiotensin-3. The encoded protein is inhibited by the aminopeptidase inhibitor amastatin, as well as by the general inhibitors o-phenanthroline and batimastat. Defects in this gene may be associated with lung tumorigenesis. [provided by RefSeq, Oct 2016]

ACMG classification

Our verdict: Benign. The variant received -13 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=9.033858E-7).
• BP6: Variant 17-68250275-A-G is Benign according to our data. Variant chr17-68250275-A-G is described in ClinVar as [Benign]. Clinvar id is 3059188.Status of the report is no_assertion_criteria_provided, 0 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.92 is higher than 0.05.
