The use of either direct or indirect genetic analyses in neurology is becoming ever greater as more genes are identified thanks to the human genome project. Often the methodologies are complex and difficult to understand. The aim of this review is to present various approaches to molecular diagnosis using several different inherited neurological diseases as examples. These include inherited mitochondriopathies, monogenetic disorders like trinucleotid repeat instability syndromes, duplication anomalies and specific point mutations as well as heterogenetic diseases such as limb girdle dystrophy and familial amyotrophic lateral sclerosis. Possible pathogenetic implications can now be proposed as the basis of new therapeutic modalities.
The use of the Bacillus subtilis sacB gene as a counter-selectable marker was assessed in serogroup A and B strains of Pasteurella multocida. Expression ofsacB failed to render any of the strains sensitive to sucrose, indicating that the sacB gene can not be used as a positive selection system in P. multocida.
