Genes affected
CAMKMT (HGNC:26276): (calmodulin-lysine N-methyltransferase) This gene encodes a class I protein methyltransferase that acts in the formation of trimethyllysine in calmodulin. The protein contains a AdoMet-binding motif and may play a role in calcium-dependent signaling. [provided by RefSeq, Sep 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.650A>G (p.D217G) alteration is located in exon 8 (coding exon 8) of the CAMKMT gene. This alteration results from a A to G substitution at nucleotide position 650, causing the aspartic acid (D) at amino acid position 217 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
