The c.1520C>T (p.T507M) alteration is located in exon 8 (coding exon 8) of the SLCO3A1 gene. This alteration results from a C to T substitution at nucleotide position 1520, causing the threonine (T) at amino acid position 507 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
