Spinocerebellar Ataxia With Dysmorphism

In 2 brothers and a sister, aged 7 to 13 years, Sanchez-Corona et al. (1985) observed a seemingly 'new' autosomal recessive hereditary ataxia syndrome. Features included unusual facies (gross, rough and abundant hair, mild palpebral ptosis, thick lips, and down-curved corners of the mouth), dysarthria, delayed psychomotor development, scoliosis, foot deformities, and ataxia.
