The c.1422A>G (p.I474M) alteration is located in exon 13 (coding exon 13) of the WDR75 gene. This alteration results from a A to G substitution at nucleotide position 1422, causing the isoleucine (I) at amino acid position 474 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
