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]

BAALC-AS1 (HGNC:50461): (BAALC antisense RNA 1)

ACMG classification

Our verdict: Likely_benign. The variant received -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.34).
• BP7: Synonymous conserved (PhyloP=1.51 with no splicing effect.
