The c.1376A>G (p.Q459R) alteration is located in exon 10 (coding exon 9) of the ENTPD8 gene. This alteration results from a A to G substitution at nucleotide position 1376, causing the glutamine (Q) at amino acid position 459 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
