Ataxia, and Intellectual disability, mild

Cerebellar ataxia, mental retardation, and dysequilibrium syndrome (CAMRQ) is a genetically heterogeneous disorder characterized by congenital cerebellar ataxia and mental retardation (summary by Gulsuner et al., 2011).For a discussion of genetic heterogeneity of CAMRQ, see CAMRQ1 (OMIM ).

2-aminoadipic 2-oxoadipic aciduria is a rare disorder of lysine and hydroxylysine metabolism characterized by variable clinical presentation including hypotonia, developmental delay, mild to severe intellectual disability, ataxia, epilepsy and behavioral disorders, most commonly attention deficit hyperactivity disorder. Frequently, individuals are completely without clinical phenotype.

Megalencephalic leukoencephalopathy with subcortical cysts (MLC) is a form of leukodystrophy that is characterized by infantile-onset macrocephaly, often with mild neurologic signs at presentation (such as mild motor delay), which worsen with time, leading to poor ambulation, falls, ataxia, spasticity, increasing seizures and cognitive decline. Brain magnetic resonance imaging reveals diffusely abnormal and mildly swollen white matter as well as subcortical cysts in the anterior temporal and frontoparietal regions.

Spectrin-associated autosomal recessive cerebellar ataxia is a rare, genetic neurological disease, due to SPTBN2 mutations, characterized by global development delay in infancy, followed by childhood-onset gait ataxia with limb dysmetria and dysdiadochokinesia, mild to severe intellectual disability, development of cerebellar atrophy, and abnormal eye movements (including a convergent squint, hypometric saccades, jerky pursuit movements and incomplete range of movement).
