Ambry Genetics

Nov 11, 2024

The c.2302G>A (p.G768S) alteration is located in exon 22 (coding exon 21) of the CC2D1B gene. This alteration results from a G to A substitution at nucleotide position 2302, causing the glycine (G) at amino acid position 768 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
