The c.778C>T (p.R260C) alteration is located in exon 10 (coding exon 9) of the WDR74 gene. This alteration results from a C to T substitution at nucleotide position 778, causing the arginine (R) at amino acid position 260 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
