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]

The c.37G>T (p.V13F) alteration is located in exon 1 (coding exon 1) of the DEGS2 gene. This alteration results from a G to T substitution at nucleotide position 37, causing the valine (V) at amino acid position 13 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
