Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_203468.3(ENTPD2):c.1444C>G(p.Leu482Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000125 in 1,605,676 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L482R) has been classified as Uncertain significance.

Genes affected

ENTPD2 (HGNC:3364): (ectonucleoside triphosphate diphosphohydrolase 2) The protein encoded by this gene is the type 2 enzyme of the ecto-nucleoside triphosphate diphosphohydrolase family (E-NTPDase). E-NTPDases are a family of ecto-nucleosidases that hydrolyze 5'-triphosphates. This ecto-ATPase is an integral membrane protein. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008]

Collection Method:clinical testing

The c.1444C>G (p.L482V) alteration is located in exon 9 (coding exon 9) of the ENTPD2 gene. This alteration results from a C to G substitution at nucleotide position 1444, causing the leucine (L) at amino acid position 482 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
