title: [Microcephaly with chromosomal instability and immunodeficiency--Nijmegen syndrome].
abstract: The Nijmegen breakage syndrome (NBS) is a rare autosomal recessive disease, which belongs to the family of genetically determined instability syndromes and to the growing category of ataxia telangiectasia (AT)--related disorders. The main manifestations include pronounced microcephaly with mental retardation in most patients, "bird-like" facies, growth retardation, immunodeficiency, chromosome instability with multiple chromosome 7 and 14 rearrangements, hypersensitivity to ionizing radiation and normal AFP level. In light of high predisposition to malignancy, an accurate diagnosis is very important for the patient.
