Vibrio vulnificus is a waterborne pathogen that was responsible for an outbreak of severe soft-tissue infections among fish farmers and fish consumers in Israel. Several factors have been shown to be associated with virulence. However, the transcriptome profile of the pathogen during human infection has not been determined yet.

Patients typically present between 1 and 6 years of age with polyuria and polydipsia.
Objective: Clinical, biochemical, and genetic studies of three new cases of autosomal recessive FNDI presenting in early infancy.
Linkage and association studies in schizophrenia have repeatedly drawn attention to several chromosomal regions and to genes within them. Conflicting patterns of association and the lack of a clear functional significance of the associated variants limit the interpretation of these results. The use of rare pedigrees, where genes with a major effect cause the disorder, has been proven beneficial in studies of other complex disorders.

Because of the complexity of the inheritance of these disorders, there is an urgent need to replicate these findings and to search for additional candidate genes. The study of genetic isolates is a powerful technique that may overcome some of the obstacles caused by genetic heterogeneity and ambiguity of phenotype definition.

Here, we report previously nonperceived interrelationships between expression variations and nucleotide polymorphisms of the chromosome 7q21-22 acetylcholinesterase-paraoxonase 1 (ACHE-PON1) locus with the trait- and state-anxiety measures of 461 healthy subjects from the Health, Risk Factors, Exercise Training, and Genetics Family Study. The AChE protein controls the termination of the stress-enhanced acetylcholine signaling, whereas the PON protein displays peroxidase-like activity, thus protecting blood proteins from oxidative stress damages.

We have recently identified the gene encoding for a bifunctional enzyme, UDP-N-acetylglucosamine 2 epimerase/N-acetylmannosamine kinase (GNE), as the mutated gene in the prototype form of the disease presenting quadriceps sparing, particularly common in Middle Eastern Jews. Interestingly, we have identified the homozygous M712T Middle Eastern Jewish mutation also in two unrelated Middle Eastern Moslem families.
