Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1358C>T (p.P453L) alteration is located in exon 10 (coding exon 9) of the ENTPD8 gene. This alteration results from a C to T substitution at nucleotide position 1358, causing the proline (P) at amino acid position 453 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
