Genetic Variant CHCHD4:p.Arg92Gln (chr3-14113041-C-T) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate

The NM_001098502.2(CHCHD4):c.275G>A(p.Arg92Gln) variant causes a missense change. The variant allele was found at a frequency of 0.0000998 in 1,613,874 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. 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. R92W) has been classified as Uncertain significance.

Genes affected

CHCHD4 (HGNC:26467): (coiled-coil-helix-coiled-coil-helix domain containing 4) CHCHD4, a component of human mitochondria, belongs to a protein family whose members share 6 highly conserved cysteine residues constituting a -CXC-CX(9)C-CX(9)C- motif in the C terminus (Hofmann et al., 2005 [PubMed 16185709]).[supplied by OMIM, Mar 2008]
