Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 18, 2024The c.622G>A (p.V208M) 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 622, causing the valine (V) at amino acid position 208 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
