These goats freeze when startled.

A myotonic goat can stay conscious while a CLCN1 variant makes its muscles stiffen and relax slowly after a startle.

When a myotonic goat gets startled, its legs can lock and the goat tips over—while it stays conscious.
A CLCN1 variant makes the ClC-1 muscle chloride channel harder to open, so muscle fibers stay electrically excitable and relax slowly. In the goat study, the variant shifted channel activation by +47 mV. 1
