Variant 3-101564951-C-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_017819.4(TRMT10C):c.170C>G(p.Pro57Arg) variant causes a missense change. The variant allele was found at a frequency of 0.00000342 in 1,461,786 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P57A) has been classified as Uncertain significance.

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.

The c.170C>G (p.P57R) alteration is located in exon 2 (coding exon 1) of the TRMT10C gene. This alteration results from a C to G substitution at nucleotide position 170, causing the proline (P) at amino acid position 57 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
