May 05, 2023

The c.227A>C (p.E76A) alteration is located in exon 2 (coding exon 2) of the WDR55 gene. This alteration results from a A to C substitution at nucleotide position 227, causing the glutamic acid (E) at amino acid position 76 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
