Genes affected
TRMT10B (HGNC:26454): (tRNA methyltransferase 10B) Enables tRNA (guanine-N1-)-methyltransferase activity. Predicted to be involved in mitochondrial tRNA processing. Located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]
EXOSC3 (HGNC:17944): (exosome component 3) This gene encodes a non-catalytic component of the human exosome, a complex with 3'-5' exoribonuclease activity that plays a role in numerous RNA processing and degradation activities. Related pseudogenes of this gene are found on chromosome 19 and 21. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jun 2012]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 19, 2024The c.331G>A (p.A111T) alteration is located in exon 4 (coding exon 3) of the TRMT10B gene. This alteration results from a G to A substitution at nucleotide position 331, causing the alanine (A) at amino acid position 111 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
