Ambry Genetics

Feb 05, 2024

The c.652C>T (p.R218W) alteration is located in exon 7 (coding exon 6) of the CMTR1 gene. This alteration results from a C to T substitution at nucleotide position 652, causing the arginine (R) at amino acid position 218 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
