The c.1102C>T (p.P368S) alteration is located in exon 12 (coding exon 9) of the SLC6A12 gene. This alteration results from a C to T substitution at nucleotide position 1102, causing the proline (P) at amino acid position 368 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
