The c.1802G>A (p.G601D) alteration is located in exon 6 (coding exon 5) of the WIZ gene. This alteration results from a G to A substitution at nucleotide position 1802, causing the glycine (G) at amino acid position 601 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
