Genes affected

ADAM12 (HGNC:190): (ADAM metallopeptidase domain 12) This gene encodes a member of a family of proteins that are 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. Expression of this gene has been used as a maternal serum marker for pre-natal development. Alternative splicing results in multiple transcript variants encoding different isoforms. Shorter isoforms are secreted, while longer isoforms are membrane-bound form. [provided by RefSeq, Jan 2014]

The c.2450G>A (p.R817Q) alteration is located in exon 21 (coding exon 21) of the ADAM12 gene. This alteration results from a G to A substitution at nucleotide position 2450, causing the arginine (R) at amino acid position 817 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
