Genes affected

ENPP7 (HGNC:23764): (ectonucleotide pyrophosphatase/phosphodiesterase 7) The protein encoded by this gene is an intestinal alkaline sphingomyelin phosphodiesterase that converts sphingomyelin to ceramide and phosphocholine. The encoded protein is anchored in the cell membrane, and it may function to protect the intestinal mucosa from inflammation and tumorigenesis. This protein is glycosylated and also exhibits lysophosphatidylcholine hydrolase activity. [provided by RefSeq, Oct 2016]

Ambry Genetics

Oct 06, 2021

The c.845C>T (p.P282L) alteration is located in exon 3 (coding exon 3) of the ENPP7 gene. This alteration results from a C to T substitution at nucleotide position 845, causing the proline (P) at amino acid position 282 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
