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 Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PC. . Gene score misZ 3.0552 (greater than the threshold 3.09). Trascript score misZ 3.7621 (greater than threshold 3.09). GenCC has associacion of gene with pyruvate carboxylase deficiency, benign type, pyruvate carboxylase deficiency, severe neonatal type, pyruvate carboxylase deficiency, infantile form, pyruvate carboxylase deficiency disease.

BP4

Computational evidence support a benign effect (MetaRNN=0.33758155).

BP6

Variant 11-66849045-C-T is Benign according to our data. Variant chr11-66849045-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 559359.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Uncertain_significance=1}.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000453 (69/152354) while in subpopulation AFR AF= 0.00166 (69/41588). AF 95% confidence interval is 0.00134. There are 0 homozygotes in gnomad4. There are 29 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
