Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2023The c.108C>A (p.N36K) alteration is located in exon 1 (coding exon 1) of the NT5DC2 gene. This alteration results from a C to A substitution at nucleotide position 108, causing the asparagine (N) at amino acid position 36 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
