About this section


Genetics Home Reference:21 VLDLR-associated cerebellar hypoplasia is an inherited condition that affects the development of the brain. People with this condition have an unusually small and underdeveloped cerebellum, which is the part of the brain that coordinates movement. This brain malformation leads to problems with balance and coordination (ataxia) that become apparent in infancy and remain stable over time. Children with VLDLR-associated cerebellar hypoplasia may learn to walk later in childhood, usually after the age of 6, although some are never able to walk independently. In one Turkish family, affected people walk on their hands and feet (quadrupedal locomotion).

MalaCards based summary: Cerebellar Hypoplasia and Mental Retardation with or Without Quadrupedal Locomotion 1, also known as dysequilibrium syndrome, is related to cerebellar ataxia and mental retardation, and has symptoms including muscular hypotonia, gait disturbance and hyperreflexia. An important gene associated with Cerebellar Hypoplasia and Mental Retardation with or Without Quadrupedal Locomotion 1 is VLDLR (very low density lipoprotein receptor). Affiliated tissues include brain, cerebellum and eye, and related mouse phenotypes are hearing/vestibular/ear and behavior/neurological.
