Genes affected

DGAT2L6 (HGNC:23250): (diacylglycerol O-acyltransferase 2 like 6) This gene is a member of the diacylglycerol acyltransferase 2 family. The encoded protein is a putative acyltransferase and is most likely involved in the synthesis of di- or triacylglycerol, however its substrate specificity is currently unknown.
