The c.1357G>A (p.A453T) alteration is located in exon 7 (coding exon 6) of the SLCO4A1 gene. This alteration results from a G to A substitution at nucleotide position 1357, causing the alanine (A) at amino acid position 453 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
