Ambry Genetics

Apr 01, 2024

The c.1393C>T (p.R465C) alteration is located in exon 14 (coding exon 13) of the CCDC38 gene. This alteration results from a C to T substitution at nucleotide position 1393, causing the arginine (R) at amino acid position 465 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
