Collection Method: clinical testing

The c.262C>T (p.R88C) alteration is located in exon 3 (coding exon 3) of the WDR38 gene. This alteration results from a C to T substitution at nucleotide position 262, causing the arginine (R) at amino acid position 88 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
