Ambry Genetics

Feb 10, 2022

The c.1390A>C (p.S464R) alteration is located in exon 10 (coding exon 9) of the ENTPD8 gene. This alteration results from a A to C substitution at nucleotide position 1390, causing the serine (S) at amino acid position 464 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
