Ambry Genetics

Jan 20, 2023

The c.2212G>C (p.A738P) alteration is located in exon 21 (coding exon 20) of the CC2D1B gene. This alteration results from a G to C substitution at nucleotide position 2212, causing the alanine (A) at amino acid position 738 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
