Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 05, 2023The c.721G>A (p.E241K) alteration is located in exon 5 (coding exon 5) of the NT5C1A gene. This alteration results from a G to A substitution at nucleotide position 721, causing the glutamic acid (E) at amino acid position 241 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
