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

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

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.

BP4

Computational evidence support a benign effect (MetaRNN=0.10962471).

BS1

Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000109 (16/1461764) while in subpopulation AMR AF= 0.000246 (11/44708). AF 95% confidence interval is 0.000137. There are 0 homozygotes in gnomad4_exome. There are 5 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAdExome4 at 16 AD gene.

The TRIP12 c.6060G>C variant is predicted to result in the amino acid substitution p.Glu2020Asp. To our knowledge, this variant has not been reported in the literature. This variant has been reported in four individuals in the SFARI database (in genome build hg38: https://genomes.sfari.org/variant/2-229767617-C-G). This variant is reported in 0.023% of alleles in individuals of Latino descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
