Genes affected

TRIM63 (HGNC:16007): (tripartite motif containing 63) This gene encodes a member of the RING zinc finger protein family found in striated muscle and iris. The product of this gene is an E3 ubiquitin ligase that localizes to the Z-line and M-line lattices of myofibrils. This protein plays an important role in the atrophy of skeletal and cardiac muscle and is required for the degradation of myosin heavy chain proteins, myosin light chain, myosin binding protein, and for muscle-type creatine kinase.

Variant summary: TRIM63 c.805G>A (p.Glu269Lys) results in a conservative amino acid change located in the COS domain (IPR017903) 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 0.0031 in 250692 control chromosomes, predominantly at a frequency of 0.0059 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately one-fold of the estimated maximal expected allele frequency for a pathogenic variant in TRIM63 causing Hypertrophic Cardiomyopathy phenotype (0.005), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. c.805G>A has been reported in the literature in unspecified individuals affected with Hypertrophic Cardiomyopathy as well as in the control cohort, without strong evidence for causality (Chen_2012). These report(s) do not provide unequivocal conclusions about association of the variant with Hypertrophic Cardiomyopathy. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 22821932). ClinVar contains an entry for this variant (Variation ID: 806097). Based on the evidence outlined above, the variant was classified as likely benign. -
