Description

The c.1945C>T (p.R649W) alteration is located in exon 18 (coding exon 16) of the PPP6R2 gene. This alteration results from a C to T substitution at nucleotide position 1945, causing the arginine (R) at amino acid position 649 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
