The c.2665C>T (p.P889S) alteration is located in exon 25 (coding exon 25) of the WDR59 gene. This alteration results from a C to T substitution at nucleotide position 2665, causing the proline (P) at amino acid position 889 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
