Possible epistatic role of ADH7 in the protection against alcoholism.

In recent studies of the role of the alcohol dehydrogenase genes (ADH) in alcoholism the ADH1B Arg47His polymorphism appears to affect risk via a protective effect associated with the ADH1B*47His. Here we present evidence for an additional effect from outside the Class I ADH genes, presumably from functional variation at the ADH7 gene. The protective effect is restricted to one of two haplotypes identical at ADH1B but differing at an intronic SNP at ADH7 suggesting epistasis or strong linkage disequilibrium (LD).

ALFRED: the ALelle FREquency Database. Update.

Elaboration of ALFRED (http://alfred.med.yale.edu) is being continued in two directions. One of which is developing tools for efficiently annotating the entries and checking the integrity of the data already in the database while the other is to increase the quantity and accessibility of data. Information contained in ALFRED such as, polymorphic sites, number of populations and frequency tables (one sample typed for one site) has significantly increased.

ALFRED: an allele frequency database for diverse populations and DNA polymorphisms--an update.

ALFRED (the ALelle FREquency Database) is designed to store and disseminate frequencies of alleles at human polymorphic sites for multiple populations, primarily for the population genetics and molecular anthropology communities. Currently ALFRED has information on over 180 polymorphic sites for more than 70 populations. Since our initial release of the database we have focussed on increasing the quantity and quality of data, making reciprocal links between ALFRED and other related databases, and providing useful tools to make the data more comprehensible to the end user. ALFRED is accessible from the Kidd Lab home page (http://info.med.yale. edu/genetics/kkidd/) or from ALFRED directly (http://alfred.med.yale. edu/alfred/index.asp).

ALFRED: an allele frequency database for diverse populations and DNA polymorphisms.

We have developed a publicly accessible database (ALFRED, the ALlele FREquency Database) that catalogues allele frequency data for a wide range of population samples and DNA polymorphisms. This database is web-accessible through our laboratory (Kidd Lab) Web site: http://info.med.yale.edu/genetics/kkidd. ALFRED currently contains data on 60 populations and 156 genetic systems including single nucleotide polymorphisms (SNPs), short tandem repeat polymorphisms (STRPs), variable number of tandem repeats (VNTRs) and insertion-deletion polymorphisms. While data are not available for all population-DNA polymorphism combinations, over 2000 allele frequency tables have been entered. Our database is designed (i) to address our specific research requirements as well as broader scientific objectives; (ii) to allow researchers and interested educators to easily navigate and retrieve data of interest to them; and (iii) to integrate links to other related public databases such as dbSNP, GenBank and PubMed.

ALFRED: a Web-accessible allele frequency database.

We present a Web-accessible database (ALFRED) that allows public access to gene frequency data for a diverse set of population samples and genetic systems. The data in ALFRED are modeled based on the experience and needs of a single laboratory, but with the expectation that the database will meet the needs of a much broader scientific community that needs population-specific gene frequency estimates. Our database currently contains data on more than 40 populations representing most major regions of the world and data on more than 150 genetic systems including SNPs, STRPs, and insertion-deletion polymorphisms. While data are not available for all population-genetic system combinations, over 2000 allele frequency tables already exist. In this paper, we enumerate the broad needs in the scientific domain, describe their significance, and describe how we have designed the database to meet those needs. We compare our database with dbSNP, the NCBI database that has a broader but overlapping purpose.
