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

Sep 10, 2024

The c.80T>C (p.F27S) alteration is located in exon 1 (coding exon 1) of the DGAT2L6 gene. This alteration results from a T to C substitution at nucleotide position 80, causing the phenylalanine (F) at amino acid position 27 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
