Disease at a Glance

Cerebral palsy (CP) is defined as a nonprogressive but not unchanging disorder of posture or movement, caused by an abnormality of the brain and first evident at the stage of rapid brain development (Hughes and Newton, 1992). The most common forms result from factors surrounding difficulties before or at birth, such as severe perinatal asphyxia, congenital infection, prematurity, and multiple pregnancy (Blair and Stanley, 1988; Stanley, 1994). More rarely, familial clustering or absence of pre- or postpartum events indicate that there are genetic forms of the disorder (Lynex et al., 2004).Cerebral palsy can be classified according to the type of movement disorder: spastic cerebral palsy accounts for approximately 60% of cases and can be subdivided into hemiplegic, diplegic, quadriplegic, and monoplegic types, whereas other forms include athetoid/dyskinetic, ataxic (605388), and mixed (Gustavson et al., 1969).Genetic Heterogeneity of Spastic Quadriplegic Cerebral PalsySee also CPSQ2 (612900), caused by deletion of the ANKRD15 gene (KANK1; 607704) inherited on the paternal allele, and CPSQ3 (617008), caused by mutation in the ADD3 gene (601568) on 10q24.Related phenotypes that were formerly classified in the CPSQ series include spastic paraplegia-47 (SPG47; 614066), spastic paraplegia-50 (SPG50; 612936), spastic paraplegia-51 (SPG51; 613744), and spastic paraplegia-52 (614067).
