Ambry Genetics

Mar 20, 2023

The c.1106T>C (p.L369P) alteration is located in exon 9 (coding exon 9) of the CDC20B gene. This alteration results from a T to C substitution at nucleotide position 1106, causing the leucine (L) at amino acid position 369 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
