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]

Ambry Genetics

Jun 07, 2024

The c.718G>A (p.D240N) alteration is located in exon 5 (coding exon 5) of the SGPP2 gene. This alteration results from a G to A substitution at nucleotide position 718, causing the aspartic acid (D) at amino acid position 240 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
