Ambry Genetics

Feb 28, 2024

The c.1678C>T (p.R560C) alteration is located in exon 11 (coding exon 11) of the CPXM2 gene. This alteration results from a C to T substitution at nucleotide position 1678, causing the arginine (R) at amino acid position 560 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
