Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM2PP2PP3_ModeratePP5

The NM_032940.3(POLR2C):c.544G>T(p.Val182Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000031 in 1,614,084 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V182A) has been classified as Uncertain significance.

Genes affected

POLR2C (HGNC:9189): (RNA polymerase II subunit C) This gene encodes the third largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. The product of this gene contains a cysteine rich region and exists as a heterodimer with another polymerase subunit, POLR2J. These two subunits form a core subassembly unit of the polymerase. A pseudogene has been identified on chromosome 21. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 2 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 1.8647 (below the threshold of 3.09). Trascript score misZ: 1.722 (below the threshold of 3.09).

PP3

MetaRNN computational evidence supports a deleterious effect, 0.875

PP5

Variant 16-57470065-G-T is Pathogenic according to our data. Variant chr16-57470065-G-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 1256007.Status of the report is no_assertion_criteria_provided, 0 stars.
