Genes affected
METTL14 (HGNC:29330): (methyltransferase 14, N6-adenosine-methyltransferase subunit) Enables mRNA binding activity. Contributes to mRNA (2'-O-methyladenosine-N6-)-methyltransferase activity. Involved in mRNA metabolic process; negative regulation of hematopoietic progenitor cell differentiation; and positive regulation of translation. Located in nucleoplasm. Part of RNA N6-methyladenosine methyltransferase complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 13, 2023The c.691A>G (p.I231V) alteration is located in exon 8 (coding exon 8) of the METTL14 gene. This alteration results from a A to G substitution at nucleotide position 691, causing the isoleucine (I) at amino acid position 231 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
