Genes affected
PC (HGNC:8636): (pyruvate carboxylase) This gene encodes pyruvate carboxylase, which requires biotin and ATP to catalyse the carboxylation of pyruvate to oxaloacetate. The active enzyme is a homotetramer arranged in a tetrahedron which is located exclusively in the mitochondrial matrix. Pyruvate carboxylase is involved in gluconeogenesis, lipogenesis, insulin secretion and synthesis of the neurotransmitter glutamate. Mutations in this gene have been associated with pyruvate carboxylase deficiency. Alternatively spliced transcript variants with different 5' UTRs, but encoding the same protein, have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.031395108).
BP6
Variant 11-66848974-C-G is Benign according to our data. Variant chr11-66848974-C-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 570839.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00019 (29/152256) while in subpopulation AFR AF= 0.000699 (29/41466). AF 95% confidence interval is 0.000499. There are 0 homozygotes in gnomad4. There are 13 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
