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]

The c.326A>T (p.K109I) alteration is located in exon 3 (coding exon 2) of the AMZ2 gene. This alteration results from a A to T substitution at nucleotide position 326, causing the lysine (K) at amino acid position 109 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
