Genes affected

ADAM18 (HGNC:196): (ADAM metallopeptidase domain 18) 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 biologic processes involving cell-cell and cell-matrix interactions, including fertilization, muscle development, and neurogenesis. The encoded preproprotein is proteolytically processed to generate the mature sperm surface protein. Alternative splicing results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed. [provided by RefSeq, Feb 2016]

The c.1219G>C (p.G407R) alteration is located in exon 12 (coding exon 12) of the ADAM18 gene. This alteration results from a G to C substitution at nucleotide position 1219, causing the glycine (G) at amino acid position 407 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
