The c.854G>T (p.G285V) alteration is located in exon 10 (coding exon 10) of the SLC47A1 gene. This alteration results from a G to T substitution at nucleotide position 854, causing the glycine (G) at amino acid position 285 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
