Genes affected

DEGS2 (HGNC:20113): (delta 4-desaturase, sphingolipid 2) This gene encodes a bifunctional enzyme that is involved in the biosynthesis of phytosphingolipids in human skin and in other phytosphingolipid-containing tissues. This enzyme can act as a sphingolipid delta(4)-desaturase, and also as a sphingolipid C4-hydroxylase. [provided by RefSeq, Oct 2008]

Jan 10, 2023

The c.302G>A (p.R101H) alteration is located in exon 2 (coding exon 2) of the DEGS2 gene. This alteration results from a G to A substitution at nucleotide position 302, causing the arginine (R) at amino acid position 101 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
