Overview

Andersen–Tawil syndrome may be classified according to genetic mutations into two groups: Type 1 Andersen–Tawil syndrome and type 2 Andersen–Tawil syndrome

[1][2]

Classification

There is no established system for the classification of [disease name].

OR

Andersen–Tawil syndrome may be classified according to genetic mutations into two groups:[3][4][5]


Type Gene involved Protein involved Location Inheritance pattern
Andersen–Tawil syndrome (ATS) 1 KCNJ2 gene (60%) Kir2.1 inward rectifier potassium channel 17q24.3 Autosomal dominant
Andersen–Tawil syndrome (ATS) 2 Unknown gene defect (40%) Kir2.1 inward rectifier potassium channel 17q24.3 Autosomal dominant

[Disease name] may be classified into [large number > 6] subtypes based on:

  • [Classification method 1]
  • [Classification method 2]
  • [Classification method 3]

[Disease name] may be classified into several subtypes based on:

  • [Classification method 1]
  • [Classification method 2]
  • [Classification method 3]
