Linkage studies of families ascertained through patients with juvenile myoclonic epilepsy (JME) suggest that an HLA-linked susceptibility gene on chromosome 6, designated "EJM1," predisposes to a group of idiopathic generalized epilepsies (IGEs) comprising JME, juvenile absence epilepsy (JAE), childhood absence epilepsies (CAE), and epilepsies with generalized tonic-clonic seizures (GTCS). To explore the EJM1-related phenotypic spectrum, we conducted linkage studies with HLA-DQ alpha restriction fragment length polymorphisms in 44 families ascertained through patients with CAE or JAE. Our results for the entire group of families provide evidence against a major susceptibility locus for idiopathic absence epilepsies and broader spectra of IGEs in the HLA region. Lod scores less than -2 were obtained for a region from 10 cM up to 23 cM on either side of the HLA-DQ alpha locus, depending on the assumed trait model. Suggestive evidence for linkage was found only for a subgroup of families with JME patients assuming an autosomal dominant mode of inheritance with 70% penetrance. A maximum lod score was obtained when family members with JME, JAE, CAE, and idiopathic GTCS were included into the affection status. Our results demonstrate that (1) the genetic susceptibility to idiopathic absence epilepsies and broader spectra of IGEs is heterogeneous, (2) the gene effect of EJM1 depends on the familial genetic background, and (3) EJM1 confers genetic susceptibility to idiopathic absence epilepsies and broader spectra of IGEs in the presence of family members with JME.

Cavernous malformations of the brain are vascular lesions which are present in up to 0.4% of all individuals and which are often accompanied by seizures, migraine, hemorrhage and other neurologic problems. Using linkage analysis and a set of short tandem repeat polymorphisms, a gene responsible for cavernous malformations in a large Hispanic kindred was mapped to the q11-q22 region of chromosome 7. A maximum pairwise lod score of 4.2 was obtained at zero recombination with marker PY5-18 at locus D7S804. Lod scores in excess of 3.0 were obtained with four additional markers closely linked to PY5-18. A broad chromosome 7q haplotype of 33 cM length on the sex average map was shared by all affected individuals indicating that the gene lies between loci D7S502 and D7S479.

Lod, a city near Tel-Aviv, is considered the main drug distribution center in Israel. A major police undercover operation in Lod, lasting close to a year, was terminated in May 2003. The success or failure of such an operation is frequently measured by the number of arrests made, the hierarchical level of the dealers arrested, the number of drug stations closed down, and the decrease in heroin seizures following the operation. In this work we suggest using an additional parameter, which has a scientific, objective basis, namely, comparing the changes in the average user weight unit ("dose") before and after the operation. We found that prior to the operation the average weight per unit was 1.1 g. Three months after the operation terminated the average weight per unit had decreased to 0.8 g and remained there for at least 4 months before rising again.
