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 Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=7.763491E-5).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.385 is higher than 0.05.
