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.280C>A (p.H94N) alteration is located in exon 4 (coding exon 4) of the DGAT2L6 gene. This alteration results from a C to A substitution at nucleotide position 280, causing the histidine (H) at amino acid position 94 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
