Collection Method:clinical testing

The c.1258A>G (p.S420G) alteration is located in exon 9 (coding exon 8) of the ENTPD8 gene. This alteration results from a A to G substitution at nucleotide position 1258, causing the serine (S) at amino acid position 420 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
