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]

Collection Method: clinical testing

The c.64C>T (p.L22F) alteration is located in exon 2 (coding exon 1) of the AMZ2 gene. This alteration results from a C to T substitution at nucleotide position 64, causing the leucine (L) at amino acid position 22 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
