Genes affected

METTL22 (HGNC:28368): (methyltransferase 22, Kin17 lysine) This gene encodes a member of the non-histone lysine methyltransferases. It interacts with its substrate, Kin17, which is involved in DNA repair and replication and mRNA processing. Alternative splicing results in multiple transcript variants.

Ambry Genetics

Jun 07, 2024

The c.20C>T (p.A7V) alteration is located in exon 2 (coding exon 1) of the METTL22 gene. This alteration results from a C to T substitution at nucleotide position 20, causing the alanine (A) at amino acid position 7 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
