Genes affected

ENTPD7 (HGNC:19745): (ectonucleoside triphosphate diphosphohydrolase 7) This gene encodes a purine-converting ectoenzyme which belongs to the ecto-nucleoside triphosphate diphosphohydrolase (E-NTPDase) family. The encoded protein hydrolyzes extracellular nucleoside triphosphates (UTP, GTP, and CTP) to nucleoside monophosphates as part of a purinergic signaling pathway. It contains two transmembrane domains at the N- and C-termini and a large, hydrophobic catalytic domain located in between. This gene affects oxidative stress as well as DNA damage and is a mediator of senescence. [provided by RefSeq, Mar 2017]

Collection Method: clinical testing

The c.599T>C (p.F200S) alteration is located in exon 6 (coding exon 5) of the ENTPD7 gene. This alteration results from a T to C substitution at nucleotide position 599, causing the phenylalanine (F) at amino acid position 200 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
