The c.53C>A (p.S18Y) alteration is located in exon 5 (coding exon 1) of the UTS2B gene. This alteration results from a C to A substitution at nucleotide position 53, causing the serine (S) at amino acid position 18 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
