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.913C>T (p.P305S) alteration is located in exon 11 (coding exon 11) of the ADAM18 gene. This alteration results from a C to T substitution at nucleotide position 913, causing the proline (P) at amino acid position 305 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
