Genes affected

ADAM8 (HGNC:215): (ADAM metallopeptidase domain 8) 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 protein encoded by this gene may be involved in cell adhesion during neurodegeneration, and it is thought to be a target for allergic respiratory diseases, including asthma. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2009]

The c.1949C>T (p.A650V) alteration is located in exon 19 (coding exon 19) of the ADAM8 gene. This alteration results from a C to T substitution at nucleotide position 1949, causing the alanine (A) at amino acid position 650 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
