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.

May 20, 2023

Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt TRMT10C protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant has not been reported in the literature in individuals affected with TRMT10C-related conditions. This variant is present in population databases (rs764404101, gnomAD 0.02%). This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 109 of the TRMT10C protein (p.Pro109Ser). -
