The c.196A>G (p.S66G) alteration is located in exon 2 (coding exon 1) of the WWTR1 gene. This alteration results from a A to G substitution at nucleotide position 196, causing the serine (S) at amino acid position 66 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
