Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.658G>A (p.E220K) 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 658, causing the glutamic acid (E) at amino acid position 220 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
