The c.1642T>A (p.C548S) alteration is located in exon 9 (coding exon 9) of the ZSWIM2 gene. This alteration results from a T to A substitution at nucleotide position 1642, causing the cysteine (C) at amino acid position 548 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
