H-abc/Tubb4a is one of many leukodystrophies. Leukodystrophy describes a group of more than 50 inherited neurological disorders. These diseases affect myelin, the protective covering on nerve cells in the brain and spine. Leukodystrophies cause a progressive loss of neurological function in infants, children and sometimes adults. Leukodystrophies affect about 1 in 7,000 live births. As we progress through the month of September we will provide more details on H-abc and leukodystrophies and what they mean for our families waiting for a cure.
