Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 12, 2023The c.2073G>C (p.K691N) alteration is located in exon 12 (coding exon 11) of the SLC6A16 gene. This alteration results from a G to C substitution at nucleotide position 2073, causing the lysine (K) at amino acid position 691 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
