Genes affected
TRMT1L (HGNC:16782): (tRNA methyltransferase 1 like) This gene encodes a protein that has some similarity to N2,N2-dimethylguanosine tRNA methyltransferase from other organisms. Studies of the mouse ortholog have shown that this protein plays a role in motor coordination and exploratory behavior, and it may also be involved in modulating postnatal neuronal functions. Alternatively spliced transcripts have been identified for this gene. [provided by RefSeq, Jan 2011]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 31, 2023The c.1330G>A (p.A444T) alteration is located in exon 10 (coding exon 10) of the TRMT1L gene. This alteration results from a G to A substitution at nucleotide position 1330, causing the alanine (A) at amino acid position 444 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
