Episodic Ataxia, Type 1; Ea1

Description

Episodic ataxia is a neurologic condition characterized by spells of incoordination and imbalance, often associated with progressive ataxia (Jen et al., 2007). Genetic Heterogeneity of Episodic AtaxiaEpisodic ataxia is a genetically heterogeneous disorder. See also EA2 (OMIM ), caused by mutation in the CACNA1A gene (OMIM ) on chromosome 19p13; EA3 (OMIM ), which maps to chromosome 1q42; EA4 (OMIM ); EA5, caused by mutation in the CACNB4 gene (OMIM ) on chromosome 2q22-q23; EA6 (OMIM ), caused by mutation in the SLC1A3 gene (OMIM ) on chromosome 5p13; EA7 (OMIM ), which maps to chromosome 19q13; and EA8 (OMIM ), which maps to chromosome 1p36-p34.Isolated myokymia-2 (see {121200}) is associated with mutation in the KCNQ2 gene (OMIM ).
