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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.424G>A (p.V142M) 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 424, causing the valine (V) at amino acid position 142 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
