Cntnap4 is a member of a family of proteins that play important role in myelinated axons [48], which is interesting given earlier evidence of myelin plasticity in the amygdala after methylone treatment [21], the potential role of activity dependent myelin plasticity in shaping neuronal connections [49, 50], and myelin changes observed in PTSD [51]. The gene discussed is CNTNAP4; the disease is post-traumatic stress disorder.
