Genes affected
METTL1 (HGNC:7030): (methyltransferase 1, tRNA methylguanosine) This gene is similar in sequence to the S. cerevisiae YDL201w gene. The gene product contains a conserved S-adenosylmethionine-binding motif and is inactivated by phosphorylation. Alternative splice variants encoding different protein isoforms have been described for this gene. A pseudogene has been identified on chromosome X. [provided by RefSeq, Jul 2008]
EEF1AKMT3 (HGNC:24936): (EEF1A lysine methyltransferase 3) Enables heat shock protein binding activity and protein-lysine N-methyltransferase activity. Involved in peptidyl-lysine methylation. Located in several cellular components, including centrosome; chromosome; and nucleoplasm. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 15, 2023The c.37G>A (p.A13T) alteration is located in exon 1 (coding exon 1) of the METTL1 gene. This alteration results from a G to A substitution at nucleotide position 37, causing the alanine (A) at amino acid position 13 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
