The c.1386C>A (p.F462L) alteration is located in exon 12 (coding exon 11) of the SLC6A13 gene. This alteration results from a C to A substitution at nucleotide position 1386, causing the phenylalanine (F) at amino acid position 462 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
