Definisjon

Inherited congenital spastic tetraplegia is a rare, genetic, neurological disease characterized by non-progressive, variable spastic quadriparesis in multiple members of a family, in the absence of additional factors complicating pregnancy or birth (e.g. perinatal asphyxia, congenital infection).
