Variant summary

Our verdict is Uncertain significance. The variant received 5 ACMG points: 6P and 1B. PM5PP3_StrongBS1_Supporting

The NM_004551.3(NDUFS3):c.596G>A(p.Arg199Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000459 in 1,613,952 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 13/22 in silico tools predict a damaging 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. R199W) has been classified as Likely pathogenic.

Genes affected

NDUFS3 (HGNC:7710): (NADH:ubiquinone oxidoreductase core subunit S3) This gene encodes one of the iron-sulfur protein (IP) components of mitochondrial NADH:ubiquinone oxidoreductase (complex I). Mutations in this gene are associated with Leigh syndrome resulting from mitochondrial complex I deficiency.[provided by RefSeq, Apr 2009]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

PM5

Other missense variant is known to change same aminoacid residue: Variant chr11-47582436-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 6020.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.987

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000499 (73/1461772) while in subpopulation SAS AF = 0.000383 (33/86248). AF 95% confidence interval is 0.00028. There are 0 homozygotes in GnomAdExome4. There are 40 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
