Ambry Genetics

Aug 14, 2024

The c.839C>T (p.A280V) alteration is located in exon 7 (coding exon 6) of the CCDC63 gene. This alteration results from a C to T substitution at nucleotide position 839, causing the alanine (A) at amino acid position 280 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
