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 GeneticsJun 06, 2023The c.429G>T (p.K143N) alteration is located in exon 3 (coding exon 2) of the METTL22 gene. This alteration results from a G to T substitution at nucleotide position 429, causing the lysine (K) at amino acid position 143 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
