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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 27, 2024The c.328G>A (p.E110K) alteration is located in exon 3 (coding exon 2) of the METTL22 gene. This alteration results from a G to A substitution at nucleotide position 328, causing the glutamic acid (E) at amino acid position 110 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
