Genes affected
SUCLG1 (HGNC:11449): (succinate-CoA ligase GDP/ADP-forming subunit alpha) This gene encodes the alpha subunit of the heterodimeric enzyme succinate coenzyme A ligase. This enzyme is targeted to the mitochondria and catalyzes the conversion of succinyl CoA and ADP or GDP to succinate and ATP or GTP. Mutations in this gene are the cause of the metabolic disorder fatal infantile lactic acidosis and mitochondrial DNA depletion. [provided by RefSeq, Feb 2010]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.11008805).
BP6
Variant 2-84431612-C-T is Benign according to our data. Variant chr2-84431612-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 579004.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000388 (59/152078) while in subpopulation AFR AF = 0.00135 (56/41408). AF 95% confidence interval is 0.00107. There are 0 homozygotes in GnomAd4. There are 23 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
