Collection Method: clinical testing

The c.342C>A (p.F114L) 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 342, causing the phenylalanine (F) at amino acid position 114 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
