Genes affected

ADAM28 (HGNC:206): (ADAM metallopeptidase domain 28) 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 is a lymphocyte-expressed ADAM protein. This gene is present in a gene cluster with other members of the ADAM family on chromosome 8. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2015]

Collection Method: clinical testing

The c.865C>T (p.R289C) alteration is located in exon 9 (coding exon 9) of the ADAM28 gene. This alteration results from a C to T substitution at nucleotide position 865, causing the arginine (R) at amino acid position 289 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
