The c.1264A>G (p.K422E) alteration is located in exon 9 (coding exon 9) of the CTNNAL1 gene. This alteration results from a A to G substitution at nucleotide position 1264, causing the lysine (K) at amino acid position 422 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
