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.

Ambry Genetics

Nov 07, 2023

The c.191G>C (p.S64T) alteration is located in exon 2 (coding exon 2) of the DGAT2L6 gene. This alteration results from a G to C substitution at nucleotide position 191, causing the serine (S) at amino acid position 64 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
