Closing the gaps among a web of DNA repair disorders

Closing the gaps among a web of DNA repair disorders As recently as six years ago, three human diseases with similar phenotypes were mistakenly believed to be caused by a single genetic defect. The three diseases, Ataxia‐telangiectasia, Nijmegen breakage syndrome, and an AT‐like disorder are now known, however, to have defects in three separate genes: ATM, NBS1, and MRE11. Furthermore, new recent studies have shown now that all three gene products interact; the ATM kinase phosphorylates NBS1,(1–4) which, in turn, associates with MRE11 to regulate DNA repair. Remarkably or expectedly, depending on one's point of view, the similarity in disease phenotypes is evidently due to defects in a common DNA repair pathway.

Abstract

As recently as six years ago, three human diseases with similar phenotypes were mistakenly believed to be caused by a single genetic defect. The three diseases, Ataxia‐telangiectasia, Nijmegen breakage syndrome, and an AT‐like disorder are now known, however, to have defects in three separate genes: ATM, NBS1, and MRE11. Furthermore, new recent studies have shown now that all three gene products interact; the ATM kinase phosphorylates NBS1,(1–4) which, in turn, associates with MRE11 to regulate DNA repair. Remarkably or expectedly, depending on one's point of view, the similarity in disease phenotypes is evidently due to defects in a common DNA repair pathway.
