Genes affected

ADAM20 (HGNC:199): (ADAM metallopeptidase domain 20) This gene encodes a member of the ADAM (a disintegrin and metalloprotease domain) family. Members of this family are membrane-anchored proteins structurally related to snake venom disintegrins, and have been implicated in a variety of biological processes involving cell-cell and cell-matrix interactions, including fertilization, muscle development, and neurogenesis. The expression of this gene is testis-specific. [provided by RefSeq, Jul 2008]

Ambry Genetics

Sep 16, 2021

The c.1715A>G (p.D572G) alteration is located in exon 2 (coding exon 1) of the ADAM20 gene. This alteration results from a A to G substitution at nucleotide position 1715, causing the aspartic acid (D) at amino acid position 572 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
