Variant chr14-60975478-G-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_020810.3(TRMT5):c.1441C>G(p.Pro481Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000038 in 1,605,234 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P481R) has been classified as Uncertain significance.

Genes affected

TRMT5 (HGNC:23141): (tRNA methyltransferase 5) tRNAs contain as many as 13 or 14 nucleotides that are modified posttranscriptionally by enzymes that are highly specific for particular nucleotides in the tRNA structure. TRMT5 methylates the N1 position of guanosine-37 (G37) in selected tRNAs using S-adenosyl methionine (Brule et al., 2004 [PubMed 15248782]).[supplied by OMIM, Mar 2008]

May 14, 2024

The c.1441C>G (p.P481A) alteration is located in exon 4 (coding exon 4) of the TRMT5 gene. This alteration results from a C to G substitution at nucleotide position 1441, causing the proline (P) at amino acid position 481 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
