Figure 2. The CNTNAP2 locus in disease and localization of its encoded product, CASPR2, at the synapse.
(A) Schematic indicating the functional relationship linking LGI1 and CASPR2 proteins through the voltage-gated potassium channel (VGKC). (B) Schematic indicating the previously reported microdeletions (horizontal bars) of CNTNAP2 in neuropsychiatric conditions (modified from Rodenas-Cuadrado, 2013). The deletion reported in this study, spanning CNTNAP2 exons 2-3, overlaps most of the CNTNAP2 deletions implicated in disorder before. It is represented in red with a halo surrounding it. ADHD = attention-deficit/hyperactivity disorder; ASD = autism spectrum disorder.
