Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2023The c.1196T>C (p.L399P) alteration is located in exon 9 (coding exon 8) of the ENTPD8 gene. This alteration results from a T to C substitution at nucleotide position 1196, causing the leucine (L) at amino acid position 399 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
