Collection Method: clinical testing

The c.643T>C (p.W215R) alteration is located in exon 4 (coding exon 4) of the SETD9 gene. This alteration results from a T to C substitution at nucleotide position 643, causing the tryptophan (W) at amino acid position 215 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
