KEGG   DISEASE: Nijmegen breakage syndrome
Entry
H01344                      Disease                                
Name
Nijmegen breakage syndrome
  Subgroup
Nijmegen breakage syndrome-like disorder (NBSLD)
  Supergrp
Immunodeficiency associated with DNA repair defects [DS:H00094]
Disorders of adaptive immunity [DS:H02526]
Primary immunodeficiency disease [DS:H01725]
Description
Nijmegen Breakage syndrome (NBS) is a rare autosomal recessive disorder characterized by microcephaly, growth retardation, immunodeficiency, radiosensitivity, and cancer predisposition. Due to a founder mutation in the NBN gene, the disease is encountered most frequently among Slavic populations. Recently, a disease due to RAD50 deficiency has been reported. The patient displayed symptoms similar to NBS, microcephaly, mental retardation, bird-like face, and short stature. The MRE11/RAD50/NBN (MRN) complex plays a key role in recognizing and signaling DNA double-strand breaks.
