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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 04, 2024The c.823C>T (p.R275W) alteration is located in exon 8 (coding exon 7) of the TRMT10A gene. This alteration results from a C to T substitution at nucleotide position 823, causing the arginine (R) at amino acid position 275 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
