The c.3257T>A (p.F1086Y) alteration is located in exon 26 (coding exon 25) of the SLC9C1 gene. This alteration results from a T to A substitution at nucleotide position 3257, causing the phenylalanine (F) at amino acid position 1086 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
