not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2024The c.1796C>A (p.T599K) alteration is located in exon 11 (coding exon 10) of the SLC6A16 gene. This alteration results from a C to A substitution at nucleotide position 1796, causing the threonine (T) at amino acid position 599 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
