Ambry Genetics

Dec 16, 2022

The c.1358T>C (p.L453S) alteration is located in exon 10 (coding exon 10) of the CTNNAL1 gene. This alteration results from a T to C substitution at nucleotide position 1358, causing the leucine (L) at amino acid position 453 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
