Collection Method: clinical testing

The c.1982A>T (p.N661I) alteration is located in exon 12 (coding exon 12) of the SLCO6A1 gene. This alteration results from a A to T substitution at nucleotide position 1982, causing the asparagine (N) at amino acid position 661 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
