Collection Method: clinical testing

The c.290G>A (p.G97D) alteration is located in exon 2 (coding exon 1) of the WWTR1 gene. This alteration results from a G to A substitution at nucleotide position 290, causing the glycine (G) at amino acid position 97 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
