Hereditary neuralgic amyotrophy (HNA) is an autosomal-dominant disorder associated with recurrent, episodic, painful, brachial neuropathy. The gene for HNA has been mapped to chromosome 17q25. Characteristic features including hypotelorism , short stature, and cleft palate occur in some patients. The phenotypic consequences of the mutant hereditary neuralgic atrophy gene may include a wider spectrum than previously appreciated and involve nonneural tissue. |
