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.

The c.719C>T (p.T240M) alteration is located in exon 6 (coding exon 6) of the DGAT2L6 gene. This alteration results from a C to T substitution at nucleotide position 719, causing the threonine (T) at amino acid position 240 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
