Genes affected
ADAM2 (HGNC:198): (ADAM metallopeptidase domain 2) 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 encoded protein is a subunit of an integral sperm membrane glycoprotein called fertilin, which plays an important role in sperm-egg interactions. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2013]

The c.1561G>A (p.V521I) alteration is located in exon 15 (coding exon 15) of the ADAM2 gene. This alteration results from a G to A substitution at nucleotide position 1561, causing the valine (V) at amino acid position 521 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
