Mutations associated with inheritable diseases are numbered in MIM notation as described in McKusick, V. A. Mendelian Inheritance in Man. A Catalog of Human Genes and Genetic Disorders, 12th edn. Baltimore Johns Hopkins University Press, 1998. An updated Internet version is found at Online Mendelian Inheritance in Man, OMIM .

Three different rare genetic metabolic defects in sialic acid metabolism are known, as indicated in Fig. 4.3.2 [3, 21] (1) free sialic acid storage disease (SASD Online Mendelian Inheritance in Man, OMIM 604369, 269920), a lysosomal membrane transporter defect (2) sialuria (OMIM 269921), a feedback inhibition defect in sialic acid biosynthesis (3) sialidosis (OMIM 256550), a breakdown defect of sialyloli-gosaccharides caused by a defect of lysosomal sialidase. In all these genetic defects, an increased amount of sialic acid can be found in tissues and or body fluids, either bound to OGSs as in (3), or in its free state as in (1) and (2).

Welcome to O fflLl, Online Mendelian Inheritance in Man. This database is a catalog of human genes and genetic disorders authored and edited by Dr. Victor A. McKusick and his colleagues at Johns Hopkins and elsewhere, and developed for the World Wide Web by NCBL the National Center for Biotechnology Information. The database contains textual information and references. It also contains copious links to MEDLINE and sequence records in the Entrez system, and links to additional related resources atNCBI and elsewhere. 

At present it has been postulated that between 30-50 and 95% of the population risk for development of AD may be attributed to genetic factors (21,24). However, when the autosomal dominant mutation cases of high penetrance are considered, that percentage drops to less than 5% (21). The most comprehensive and current lists of all mutations that may be considered as AD genetic determinants or risk factors are maintained by Online Mendelian Inheritance in Man (OMIM) (25) and Alzheimer Disease Mutation Database (ADMB) (26).
