How Defective DNA Repair Triggers Two Neurological Diseases

Scientists at St. Jude Children’s Research Hospital have teased apart the biological details distinguishing two related neurological diseases — ataxia telangiectasia-like disease (ATLD) and Nijmegen breakage syndrome (NBS). Both disorders arise from defects in a central component of the cell’s machinery that repairs damaged DNA, but each disease presents with distinct pathologies. Defects in DNA [...]

Just as its symptoms vary widely among individuals, so do the genetic mutations that cause them. Now, Howard Hughes Medical Institute investigator Christopher Walsh, in collaboration with scientists and physicians in the United States, Turkey, [...]
