Genes affected

TRMT10A (HGNC:28403): (tRNA methyltransferase 10A) This gene encodes a protein that belongs to the tRNA (Guanine-1)-methyltransferase family. A similar gene in yeast modifies several different tRNA species. Mutations in this gene are associated with microcephaly, short stature, and impaired glucose metabolism. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2014]

This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 69 of the TRMT10A protein (p.Arg69Leu). This variant is present in population databases (rs147815779, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with TRMT10A-related conditions. ClinVar contains an entry for this variant (Variation ID: 1434172). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt TRMT10A protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
