The c.1278G>C (p.W426C) alteration is located in exon 11 (coding exon 11) of the WDR46 gene. This alteration results from a G to C substitution at nucleotide position 1278, causing the tryptophan (W) at amino acid position 426 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
