Genes affected

POLR3A (HGNC:30074): (RNA polymerase III subunit A) The protein encoded by this gene is the catalytic component of RNA polymerase III, which synthesizes small RNAs. The encoded protein also acts as a sensor to detect foreign DNA and trigger an innate immune response. [provided by RefSeq, Aug 2011]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -14 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.89).

BP6

Variant 10-77975439-G-A is Benign according to our data. Variant chr10-77975439-G-A is described in ClinVar as Likely_benign. ClinVar VariationId is 300985.Status of the report is criteria_provided_single_submitter, 1 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00408 (622/152286) while in subpopulation AFR AF = 0.0142 (588/41544). AF 95% confidence interval is 0.0132. There are 6 homozygotes in GnomAd4. There are 286 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 6 AR gene
