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]

The c.1331G>T (p.G444V) alteration is located in exon 11 (coding exon 11) of the METTL14 gene. This alteration results from a G to T substitution at nucleotide position 1331, causing the glycine (G) at amino acid position 444 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
