Ambry Genetics

Dec 08, 2023

The c.220C>T (p.R74C) alteration is located in exon 4 (coding exon 1) of the CCDC102B gene. This alteration results from a C to T substitution at nucleotide position 220, causing the arginine (R) at amino acid position 74 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
