Genes affected
SGPP2 (HGNC:19953): (sphingosine-1-phosphate phosphatase 2) The protein encoded by this gene is a transmembrane protein that degrades the bioactive signaling molecule sphingosine 1-phosphate. The encoded protein is induced during inflammatory responses and has been shown to be downregulated by the microRNA-31 tumor suppressor. Alternative splice variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 05, 2024The c.616A>G (p.S206G) alteration is located in exon 4 (coding exon 4) of the SGPP2 gene. This alteration results from a A to G substitution at nucleotide position 616, causing the serine (S) at amino acid position 206 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
