Genes affected

ADAM21 (HGNC:200): (ADAM metallopeptidase domain 21) 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 expression is testis-specific. [provided by RefSeq, May 2011]

The c.1216C>G (p.L406V) alteration is located in exon 2 (coding exon 1) of the ADAM21 gene. This alteration results from a C to G substitution at nucleotide position 1216, causing the leucine (L) at amino acid position 406 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
