Variant summary
Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1PM2PP3_StrongPP5
The NM_016035.5(COQ4):c.437T>G(p.Phe146Cys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000346 in 1,446,250 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. F146F) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 18, 2022 | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 488487). This missense change has been observed in individuals with coenzyme Q10 deficiency (PMID: 32860008, 33215859). This variant is present in population databases (no rsID available, gnomAD no frequency). This sequence change replaces phenylalanine, which is neutral and non-polar, with cysteine, which is neutral and slightly polar, at codon 146 of the COQ4 protein (p.Phe146Cys). - |
Likely pathogenic, criteria provided, single submitter | clinical testing | Neuberg Centre For Genomic Medicine, NCGM | - | The missense variant p.F146C in COQ4 (NM_016035.5) has been previously reported (Bertoli-Avella AM et al). The variant has been submitted to ClinVar as Pathogenic/Likely pathogenic and Uncertain Significance. The p.F146C variant is observed in 1/2,25,000 (0.0004%) alleles from individuals of all background in gnomAD Exomes and is novel (not in any individuals) in 1000 Genomes. The p.F146C missense variant is predicted to be damaging by both SIFT and PolyPhen2. The phenylalanine residue at codon 146 of COQ4 is conserved in all mammalian species. The nucleotide c.437 in COQ4 is predicted conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Likely Pathogenic. - |
