Ambry Genetics

Jul 15, 2021

The c.2327G>A (p.R776Q) alteration is located in exon 6 (coding exon 5) of the CCDC80 gene. This alteration results from a G to A substitution at nucleotide position 2327, causing the arginine (R) at amino acid position 776 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
