Hereditary hemochromatosis in adults is usually characterized by mutations in the hemochromatosis (HFE) gene on the short arm of chromosome 6. Most patients have a substitution of tyrosine for cysteine at position 282 (C282Y). We studied a large family from Italy that includes persons who have a hereditary iron-overload condition indistinguishable from hemochromatosis but without apparent pathogenic mutations in the HFE gene. We performed biochemical, histologic, and genetic studies of 53 living members of the family, including microsatellite analysis of chromosome 6 and direct sequencing of the HFE gene.

Microorganisms represent most of the biodiversity of living organisms in every ecological habitat. They have profound effects on the functioning of any ecosystem, and therefore on the health of our planet and of human beings. Moreover, microorganisms are the main protagonists in food, medical and biotech industries, and have several environmental applications. Accordingly, the characterization and preservation of microbial biodiversity are essential not only for the maintenance of natural ecosystems but also for research purposes and biotechnological exploitation. In this context, culture collections (CCs) and microbial biological resource centres (mBRCs) are crucial for the safeguarding and circulation of biological resources, as well as for the progress of life sciences. This review deals with the expertise and services of CCs, in particular concerning preservation and characterization of microbial resources, by pointing to the advanced approaches applied to investigate a huge reservoir of microorganisms. Data sharing and web services as well as the tight interconnection between CCs and the biotechnological industry are highlighted. In addition, guidelines and regulations related to quality management systems (QMSs), biosafety and biosecurity issues are discussed according to the perspectives of CCs and mBRCs.
