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]

ENSG00000255872 (HGNC:):

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]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
