Ambry Genetics

Oct 04, 2022

The c.1447C>T (p.R483C) alteration is located in exon 19 (coding exon 19) of the CCDC93 gene. This alteration results from a C to T substitution at nucleotide position 1447, causing the arginine (R) at amino acid position 483 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
