The c.171A>C (p.R57S) alteration is located in exon 2 (coding exon 2) of the WDR75 gene. This alteration results from a A to C substitution at nucleotide position 171, causing the arginine (R) at amino acid position 57 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
