Genes affected

ADAM7 (HGNC:214): (ADAM metallopeptidase domain 7) This gene encodes a member of the ADAMs family of zinc proteases. These transmembrane proteins play roles in multiple processes including cell signaling, adhesion and migration. The encoded protein lacks protease activity and may play roles in protein-protein interactions and cell adhesion processes including sperm-egg fusion. Mutations in this gene may be involved in the progression of melanoma. [provided by RefSeq, Oct 2011]

ADAM7-AS2 (HGNC:56153): (ADAM7 antisense RNA 2)

ADAM7-AS1 (HGNC:56152): (ADAM7, ADAMDEC1 and ADAM28 antisense RNA 1)

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.11893743).

The c.1364A>G (p.K455R) alteration is located in exon 14 (coding exon 14) of the ADAM7 gene. This alteration results from a A to G substitution at nucleotide position 1364, causing the lysine (K) at amino acid position 455 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
