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.

The c.382C>T (p.P128S) alteration is located in exon 3 (coding exon 2) of the METTL22 gene. This alteration results from a C to T substitution at nucleotide position 382, causing the proline (P) at amino acid position 128 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
