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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.2196G>T (p.K732N) alteration is located in exon 19 (coding exon 19) of the ADAM12 gene. This alteration results from a G to T substitution at nucleotide position 2196, causing the lysine (K) at amino acid position 732 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
