RESUMEN
Los síndromes de inestabilidad cromosómica son causados por fallas en la reparación del ADN y en la respuesta ante daño. Estas enfermedades pertenecen al grupo de inmunodeficiencias primarias asociadas a síndromes bien definidos, debido a que presentan alteraciones en el sistema inmunitario. Adicionalmente muestran alteraciones en la estructura y comportamiento de los cromosomas, por lo que su identificación requiere métodos citogenéticos. El diagnóstico de estos desórdenes representa un reto ya que involucra la participación de especialistas tanto en Inmunología como en Genética. En este trabajo se hace una revisión de los síndromes: Ataxia Telangiectasia, Nijmegen, Bloom e ICF, enfatizando en los aspectos citogenéticos, a fin de ofrecer información sobre las bases del diagnóstico de estas enfermedades.
