Are some types of episodic ataxia rarer than others?

Some types of EA are so rare that experts have only identified them in one or two families. These include:

  • Episodic ataxia type 3 (EA3).
  • Episodic ataxia type 4 (EA4).
  • Episodic ataxia type 5 (EA5).
  • Episodic ataxia type 6 (EA6).
  • Episodic ataxia type 7 (EA7).
  • Episodic ataxia type 8 (EA8).

Researchers have identified some of the genes associated with these EA types. But they're still learning about others.
