Variant 9-100578304-T-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_001018116.2(CAVIN4):c.161T>G(p.Ile54Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000248 in 1,613,866 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I54T) has been classified as Uncertain significance.

Genes affected

CAVIN4 (HGNC:33742): (caveolae associated protein 4) This gene encodes a protein containing two coiled-coil regions. The encoded protein promotes Rho/ROCK (Rho-kinase) signaling in cardiac muscles cells, and may facilitate myofibrillar organization. [provided by RefSeq, Jun 2013]

Jan 16, 2017

A variant of uncertain significance has been identified in the MURC gene. The I54R variant has not been published as pathogenic or been reported as benign to our knowledge. It is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The I54R variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. Although this substitution occurs at a position where amino acids with similar properties to isoleucine (I) are tolerated across species, in silico analysis predicts this variant is probably damaging to the protein structure/function. Nonetheless, this variant lacks observation in a significant number of affected individuals, segregation data, and functional evidence, all of which would further clarify pathogenicity. -
