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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2024The c.233G>A (p.C78Y) alteration is located in exon 2 (coding exon 1) of the TRMT10C gene. This alteration results from a G to A substitution at nucleotide position 233, causing the cysteine (C) at amino acid position 78 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
