The c.559T>A (p.S187T) alteration is located in exon 3 (coding exon 2) of the STEAP1B gene. This alteration results from a T to A substitution at nucleotide position 559, causing the serine (S) at amino acid position 187 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
