Genes affected

MACC1 (HGNC:30215): (MET transcriptional regulator MACC1) MACC1 is a key regulator of the hepatocyte growth factor (HGF; MIM 142409)-HGF receptor (HGFR, or MET; MIM 164860) pathway, which is involved in cellular growth, epithelial-mesenchymal transition, angiogenesis, cell motility, invasiveness, and metastasis. Expression of MACC1 in colon cancer (MIM 114500) specimens is an independent prognostic indicator for metastasis formation and metastasis-free survival (Stein et al., 2009 [PubMed 19098908]).[supplied by OMIM, Mar 2009]

Collection Method: clinical testing

The c.2420T>C (p.L807S) alteration is located in exon 7 (coding exon 4) of the MACC1 gene. This alteration results from a T to C substitution at nucleotide position 2420, causing the leucine (L) at amino acid position 807 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
