chr9-37776303-C-T

Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 2P and 6B. PM2BP4_StrongBP6_Moderate

The NM_144964.4(TRMT10B):​c.742C>T​(p.Arg248Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000031 in 1,581,304 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R248Q) has been classified as Likely benign.

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]
