From Wikipedia, the free encyclopedia
ICF syndrome (or Immunodeficiency, Centromere instability and Facial anomalies syndrome)[1] is a very rare autosomal recessive[2] immune disorder.
[edit] Genetics
ICF syndrome has an autosomal recessive pattern of
inheritance.
ICF syndrome can be caused by a mutation in the DNA-methyltransferase-3b (Dnmt3b) gene.[3]
[edit] 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.
