Genes affected

TRIP12 (HGNC:12306): (thyroid hormone receptor interactor 12) The protein encoded by this gene is an E3 ubiquitin-protein ligase involved in the degradation of the p19ARF/ARF isoform of CDKN2A, a tumor suppressor. The encoded protein also plays a role in the DNA damage response by regulating the stability of USP7, which regulates tumor suppressor p53. [provided by RefSeq, Jan 2017]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. There are 5 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 2-229767648-T-TAGTTCACACAAGTC is Pathogenic according to our data. Variant chr2-229767648-T-TAGTTCACACAAGTC is described in ClinVar as [Likely_pathogenic]. Clinvar id is 1709873.Status of the report is criteria_provided_single_submitter, 1 stars.
