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 Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 2-229859211-ACT-A is Pathogenic according to our data. Variant chr2-229859211-ACT-A is described in ClinVar as [Pathogenic]. Clinvar id is 446136.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr2-229859211-ACT-A is described in Lovd as [Pathogenic].
