Genes affected
SGPP1 (HGNC:17720): (sphingosine-1-phosphate phosphatase 1) Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid metabolite that regulates diverse biologic processes. SGPP1 catalyzes the degradation of S1P via salvage and recycling of sphingosine into long-chain ceramides (Mandala et al., 2000 [PubMed 10859351]; Le Stunff et al., 2007 [PubMed 17895250]).[supplied by OMIM, Jun 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 01, 2022The c.1259A>G (p.Y420C) alteration is located in exon 3 (coding exon 3) of the SGPP1 gene. This alteration results from a A to G substitution at nucleotide position 1259, causing the tyrosine (Y) at amino acid position 420 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
