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]
ADAM20P1 (HGNC:20102): (ADAM metallopeptidase domain 20 pseudogene 1)

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 17, 2023The c.143T>A (p.V48E) alteration is located in exon 2 (coding exon 1) of the ADAM21 gene. This alteration results from a T to A substitution at nucleotide position 143, causing the valine (V) at amino acid position 48 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
