Ambry Genetics

Jul 27, 2024

The c.1297C>T (p.R433W) alteration is located in exon 12 (coding exon 11) of the CCDC47 gene. This alteration results from a C to T substitution at nucleotide position 1297, causing the arginine (R) at amino acid position 433 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
