Genes affected
PRKRA (HGNC:9438): (protein activator of interferon induced protein kinase EIF2AK2) This gene encodes a protein kinase activated by double-stranded RNA which mediates the effects of interferon in response to viral infection. Mutations in this gene have been associated with dystonia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2008]
