Genes affected

AAMP (HGNC:18): (angio associated migratory cell protein) The gene is a member of the immunoglobulin superfamily. The encoded protein is associated with angiogenesis, with potential roles in endothelial tube formation and the migration of endothelial cells. It may also regulate smooth muscle cell migration via the RhoA pathway. The encoded protein can bind to heparin and may mediate heparin-sensitive cell adhesion. [provided by RefSeq, Oct 2014]

Collection Method: clinical testing

The c.866C>T (p.A289V) alteration is located in exon 7 (coding exon 7) of the AAMP gene. This alteration results from a C to T substitution at nucleotide position 866, causing the alanine (A) at amino acid position 289 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
