Christ-siemens-touraine syndrome --> anhidrotic ectodermal dysplasia
symptoms include absent teeth, peg teeth, inability to sweat, thin skin and heat intolerance. Mucous membrane involvement may result in a foul-smelling nasal discharge. The inability to sweat leads to the inability to maintain normal body temperature in a warm environment. Some may exhibit fevers and will require artificial cooling.
Inheritance: mostly sex-linked (X chromosome).
