Genes affected

TRMT10C (HGNC:26022): (tRNA methyltransferase 10C, mitochondrial RNase P subunit) This gene encodes the precursor of a subunit of the mitochondrial ribonuclease P, which is involved in 5' processing of mitochondrial tRNAs. The encoded protein may confer RNA-binding capacity to mitochondrial ribonuclease P and may be essential for transcript processing, RNA modification, translation and mitochondrial respiration.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0026145875).

BP6

Variant 3-101565273-G-C is Benign according to our data. Variant chr3-101565273-G-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 377049.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0147 (2240/152228) while in subpopulation AFR AF = 0.0507 (2104/41524). AF 95% confidence interval is 0.0489. There are 50 homozygotes in GnomAd4. There are 1030 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 50 Unknown,AR gene
