Variant summary

Our verdict is Benign. Variant got -18 ACMG points: 2P and 20B. PM1BP4_StrongBP6_Very_StrongBS1BS2

The NM_016035.5(COQ4):c.483G>C(p.Glu161Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00811 in 1,613,374 control chromosomes in the GnomAD database, including 91 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E161G) has been classified as Uncertain significance.

Genes affected

COQ4 (HGNC:19693): (coenzyme Q4) This gene encodes a component of the coenzyme Q biosynthesis pathway. Coenzyme Q, an essential component of the electron transport chain, shuttles electrons between complexes I or II to complex III of the mitochondrial transport chain. This protein appears to play a structural role in stabilizing a complex that contains most of the coenzyme Q biosynthesis enzymes. Mutations in this gene are associated with mitochondrial disorders linked to coenzyme Q deficiency. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -18 ACMG points.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 6 uncertain in NM_016035.5

BP4

Computational evidence support a benign effect (MetaRNN=0.018062353).

BP6

Variant 9-128332233-G-C is Benign according to our data. Variant chr9-128332233-G-C is described in ClinVar as [Likely_benign]. Clinvar id is 380493.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr9-128332233-G-C is described in Lovd as [Benign].

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.00555 (845/152292) while in subpopulation SAS AF= 0.0104 (50/4830). AF 95% confidence interval is 0.00807. There are 6 homozygotes in gnomad4. There are 396 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

BS2
