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 Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), TRIP12. . Gene score misZ 4.6402 (greater than the threshold 3.09). Trascript score misZ 6.3495 (greater than threshold 3.09). GenCC has associacion of gene with syndromic intellectual disability, Clark-Baraitser syndrome, complex neurodevelopmental disorder.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.864
