Collection Method: clinical testing

The c.362G>A (p.R121H) alteration is located in exon 3 (coding exon 3) of the WDR55 gene. This alteration results from a G to A substitution at nucleotide position 362, causing the arginine (R) at amino acid position 121 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
