Description: (OMIM) Familial episodic pain syndrome-2 is an autosomal dominant neurologic disorder characterized by adult-onset of paroxysmal pain mainly affecting the distal lower extremities (summary by Faber et al., 2012).

Clinical Description OMIM Faber et al. (2012) reported a man who developed burning and intense paroxysmal itch in the feet at age 57 years. Nerve conduction studies were normal, but skin biopsy showed reduced intraepidermal nerve fiber density in the distal ...
Molecular genetics OMIM In a father and son with adult-onset FEPS2, Faber et al. (2012) identified a heterozygous missense mutation in the SCN10A gene (L554P; 604427.0001). An unrelated woman with a similar disorder carried a different heterozygous mutation (A1304T; 604427.0002). In ...
