Ambry Genetics

Dec 01, 2022

The c.577C>T (p.R193W) alteration is located in exon 4 (coding exon 4) of the CNTLN gene. This alteration results from a C to T substitution at nucleotide position 577, causing the arginine (R) at amino acid position 193 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
