The c.971G>A (p.S324N) alteration is located in exon 9 (coding exon 9) of the WDR46 gene. This alteration results from a G to A substitution at nucleotide position 971, causing the serine (S) at amino acid position 324 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
