Genes affected

CTHRC1 (HGNC:18831): (collagen triple helix repeat containing 1) This locus encodes a protein that may play a role in the cellular response to arterial injury through involvement in vascular remodeling. Mutations at this locus have been associated with Barrett esophagus and esophageal adenocarcinoma. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jan 2012]

The c.425G>A (p.S142N) alteration is located in exon 3 (coding exon 3) of the CTHRC1 gene. This alteration results from a G to A substitution at nucleotide position 425, causing the serine (S) at amino acid position 142 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
