Genes affected

TRIM40 (HGNC:18736): (tripartite motif containing 40) This gene encodes a member of the tripartite motif (TRIM) protein family. The encoded protein may play a role as a negative regulator against inflammation and carcinogenesis in the gastrointestinal tract. Alternatively spliced transcript variants that encode different protein isoforms have been described. [provided by RefSeq, Feb 2014]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
