ICF syndrome
Introduction
ICF syndrome (or Immunodeficiency, Centromere instability and Facial anomalies syndrome)[1] is a very rare autosomal recessive[2] immune disorder.
Genetics
Genetics
ICF syndrome can be caused by a mutation in the DNA-methyltransferase-3b (Dnmt3b) gene.[3]
Presentation
Presentation
It is characterized by variable reductions in serum immunoglobulin levels which cause most ICF patients to succumb to infectious diseases before adulthood. ICF syndrome patients exhibit facial anomalies which include hypertelorism, low-set ears, epicanthal folds and macroglossia.
