The c.2053C>T (p.P685S) alteration is located in exon 7 (coding exon 6) of the WIZ gene. This alteration results from a C to T substitution at nucleotide position 2053, causing the proline (P) at amino acid position 685 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
