The c.446T>C (p.F149S) alteration is located in exon 5 (coding exon 5) of the WDR75 gene. This alteration results from a T to C substitution at nucleotide position 446, causing the phenylalanine (F) at amino acid position 149 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
