The c.1646T>A (p.L549Q) alteration is located in exon 13 (coding exon 13) of the CTNNAL1 gene. This alteration results from a T to A substitution at nucleotide position 1646, causing the leucine (L) at amino acid position 549 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
