Alphabet soup: making sense of genetic testing in CMT

The diagnosis of inherited neuropathies can be challenging in several ways. First, a hereditary neuropathy must be suspected. Although some family histories are clear with multiple members affected, other families require directed inquiry. Second, even when a hereditary neuropathy is clear, it can be difficult to make a genetic characterization. The field of genotyping is expanding so rapidly, it is difficult to know what tests to order. The authors share their guidelines for the diagnosis of inherited neuropathies.
