Genes affected

CSKMT (HGNC:33113): (citrate synthase lysine methyltransferase) Enables protein-lysine N-methyltransferase activity. Involved in peptidyl-lysine dimethylation; peptidyl-lysine monomethylation; and peptidyl-lysine trimethylation. Predicted to be located in mitochondrion.

CSKMT links:

LBHD1 (HGNC:28351): (LBH domain containing 1) This gene shares three exons in common with another gene, chromosome 11 open reading frame 98 (GeneID:102288414), but the encoded protein uses a reading frame that is different from that of the chromosome 11 open reading frame 98 gene.
