The c.739C>A (p.L247M) alteration is located in exon 2 (coding exon 1) of the SLCO4A1 gene. This alteration results from a C to A substitution at nucleotide position 739, causing the leucine (L) at amino acid position 247 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
