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]

The c.102C>A (p.N34K) alteration is located in exon 1 (coding exon 1) of the SGPP2 gene. This alteration results from a C to A substitution at nucleotide position 102, causing the asparagine (N) at amino acid position 34 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
