RCV003331094 | SCV004039555 | uncertain significance | not specified | 2023-08-15 | criteria provided, single submitter | clinical testing | Variant summary: TRIM63 c.390C>G (p.Ile130Met) results in a conservative amino acid change located in the B-box-type zinc finger domain (IPR000315) of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4.8e-05 in 251444 control chromosomes (gnomAD). This frequency is not significantly higher than estimated for a pathogenic variant in TRIM63 causing Hypertrophic Cardiomyopathy (4.8e-05 vs 0.005), allowing no conclusion about variant significance. c.390C>G has been reported in the literature in individuals affected with Hypertrophic Cardiomyopathy (Chen_2012, Al-Shafai_2021) without evidence of segregation, and was found as a de novo occurrence in an individual with Congenital Heart Disease (Edwards_2020). These data do not allow any conclusion about variant significance. Experimentally, the variant was found impacting ubiquitination in transduced HeLa cells, with the most pronounced variant effect resulting in 30%-40% of normal activity (Chen_2012). The following publications have been ascertained in the context of this evaluation (PMID: 34137518, 22821932, 32368696). No submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as VUS-possibly pathogenic. |
