The c.1447C>T (p.R483W) alteration is located in exon 10 (coding exon 10) of the SLC1A7 gene. This alteration results from a C to T substitution at nucleotide position 1447, causing the arginine (R) at amino acid position 483 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
