Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 18, 2023The c.1327A>G (p.N443D) alteration is located in exon 8 (coding exon 7) of the SLC6A16 gene. This alteration results from a A to G substitution at nucleotide position 1327, causing the asparagine (N) at amino acid position 443 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
