A global team of neuroscientists, led by researchers at Mayo Clinic in Florida, have found the gene responsible for a brain disorder that may be much more common than once believed. In the Dec. 25 online issue of Nature Genetics, the researchers say they identified 14 different mutations in the gene CSF1R that lead to development of hereditary diffuse leukoencephalopathy with spheroids (HDLS). This is a devastating disorder of the brains white matter that leads to death between ages 40 and 60. People who inherit the abnormal gene always develop HDLS. Until now, a definite diagnosis of HDLS required examination of brain tissue at biopsy or autopsy.
