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]

ENSG00000257759 (HGNC:):

ACMG classification
