Collection Method: clinical testing

The c.518C>T (p.T173I) alteration is located in exon 2 (coding exon 2) of the SLCO3A1 gene. This alteration results from a C to T substitution at nucleotide position 518, causing the threonine (T) at amino acid position 173 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
