A new syndrome characterized by mental retardation, epilepsy, palpebral conjunctival telangiectasias and IgA deficiency.

Mental retardation, epilepsy, palpebral conjunctival telangiectasias and diminished serum IgA, with a particular facies and shortened fifth finger were found in a 12-year-old Mexican girl. She has six siblings, of whom five have the same characteristics. The parents and the elder sister were not affected, and there was no history of consanguinity. This seems to be a new syndrome, and as both sexes are affected, the parents are normal and several siblings have the same syndrome, we postulate an autosomal recessive mode of inheritance.

Fourteen cases of patients with photoconvulsive response during intermitent luminous stimulation (eleven women and three men) are reviewed. The frequency of the photoconvulsive response was higher between 10 and 20 years of age (eleven cases). Most of the patients (twelve) presented some form of epilepsy and only two had psychomotor retardation without epilepsy. Comment is made on differences published by other authors and possible explanations of such differences are proposed.
