Genes affected
METTL4 (HGNC:24726): (methyltransferase 4, N6-adenosine) Enables RNA methyltransferase activity and site-specific DNA-methyltransferase (adenine-specific) activity. Involved in nucleic acid metabolic process; regulation of RNA metabolic process; and regulation of mitochondrial DNA replication. Located in cytosol; mitochondrial matrix; and nucleus.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2021The c.1234G>A (p.V412M) alteration is located in exon 8 (coding exon 7) of the METTL4 gene. This alteration results from a G to A substitution at nucleotide position 1234, causing the valine (V) at amino acid position 412 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
