Genes affected

ENPP3 (HGNC:3358): (ectonucleotide pyrophosphatase/phosphodiesterase 3) The protein encoded by this gene belongs to a series of ectoenzymes that are involved in hydrolysis of extracellular nucleotides. These ectoenzymes possess ATPase and ATP pyrophosphatase activities and are type II transmembrane proteins. Expression of the related rat mRNA has been found in a subset of immature glial cells and in the alimentary tract. The corresponding rat protein has been detected in the pancreas, small intestine, colon, and liver. The human mRNA is expressed in glioma cells, prostate, and uterus. Expression of the human protein has been detected in uterus, basophils, and mast cells. Two transcript variants, one protein coding and the other non-protein coding, have been found for this gene.

Ambry Genetics

Jun 09, 2022

The c.104T>C (p.M35T) alteration is located in exon 2 (coding exon 2) of the ENPP3 gene. This alteration results from a T to C substitution at nucleotide position 104, causing the methionine (M) at amino acid position 35 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
