Ambry Genetics

Apr 24, 2024

The c.2425T>C (p.C809R) alteration is located in exon 23 (coding exon 22) of the CC2D1B gene. This alteration results from a T to C substitution at nucleotide position 2425, causing the cysteine (C) at amino acid position 809 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
