She developed severe intractable myoclonic seizures at age 4 months, consistent with epileptic encephalopathy. Feinberg and Leahy described an X-linked recessive form of the disorder, suggesting a specific genetic entity.

X linked mental retardation and infantile spasms in a family: Their data supported a multifactorial model involving polygenic determination of susceptibility and requiring additional environmental factors such as anoxia, birth trauma, or immunization. These 2 patients were hemizygous for the same de novo bp duplication in exon 2 of the ARX gene Three children had recurrent, life-threatening status dystonicus. You may also be interested in: Overall methodology of the studies was poor, in part because of ethical dilemmas such as giving placebo injections to children.

In the majority, methodology has been spasm, hence it is not clear which treatment is optimal in the treatment of this epilepsy syndrome. In affected members of a family with X-linked myoclonic epilepsy with spasticity and mental retardation, Scheffer et al. Mutations of ARX are associated with striking pleiotropy and consistent genotype-phenotype correlation. The disorder was characterized by infantile spasms, hypsarrhythmia on EEG, and developmental arrest leading to severe to profound mental retardation.

Analysis included assessment of study quality and a search for sources of heterogeneity. Both boys presented in early infancy with spasms associated with myoclonic jerks or clonic attacks. Associations Pending Confirmation See One of the boys had poor overall growth, and both developed progressive microcephaly associated with intellectual impairment and spastic tetraparesis.

X-linked myoclonic epilepsy with spasticity and intellectual disability: She was the product of a twin pregnancy conceived by in vitro fertilization with a donor egg and the father’s sperm.

Hormonal treatment resolves spasms in more infants than vigabatrin, but this may or may not translate into better long-term outcomes.

Two studies have shown that a placebo is not as good as an active treatment in resolving the spasms.

If prednisolone or vigabatrin is used, high dosage is recommended. EIEE1 is part of a phenotypic spectrum of disorders caused by mutation in the ARX gene comprising a nearly continuous series of developmental disorders ranging from lissencephaly LISX2; to Proud syndrome to infantile spasms without brain malformations EIEE1 to syndromic and nonsyndromic mental retardation.

These 18 studies looked at a total of patients treated with a total of 12 different pharmaceutical agents.
