Collection Method: clinical testing

The c.286C>T (p.R96W) alteration is located in exon 3 (coding exon 3) of the CAND2 gene. This alteration results from a C to T substitution at nucleotide position 286, causing the arginine (R) at amino acid position 96 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
