Classification

Two types of Andersen-Tawil syndrome are distinguished by their genetic causes.

  • Type 1, which accounts for about 60 percent of all cases of the disorder, is caused by mutations in the KCNJ2 gene. [1][2]
  • The remaining 40 percent of cases are designated as type 2; the cause of the condition in these cases is unknown.
