Collection Method: clinical testing

The c.1096G>A (p.A366T) alteration is located in exon 12 (coding exon 9) of the SLC6A12 gene. This alteration results from a G to A substitution at nucleotide position 1096, causing the alanine (A) at amino acid position 366 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
