These data are genetic sequences for 387 individuals from a study of Crohn's disease, which is an inflammatory bowel disease (Daly et al., 2001a, Nature Genetics, 29, 223-228). The data are in a text-based LINKAGE format.
Name: pedigree
Type: character
Description: The pedigree of the individual (which genetic family tree the individual belongs to).
Name: ID
Type: integer (min: 0)
Description: A unique identifier for the individual.
Name: parentA
Type: integer (min: 0)
Description: The identifier for one parent.
Name: parentB
Type: integer (min: 0)
Description: The identifier for the other parent.
Name: gender
Type: categorical ( 1 means male, 2 means female )
Description: The individual's gender.
Name: status
Type: categorical ( 0 means unknown, 1 means crohnsnormal )
Description: Whether the individual has Crohn's disease.
Name: marker1A to marker103B
Type: integer (min: 0)
Description: The genotype for the individual at 103 different locations. marker1A gives the individual's first allele at locus 1 and marker1B gives the individual's second allele at locus 1 and so on.
The data set is provided as a tab-delimited ASCII text file called Dalydata.txt. The format is designed for use with the LINKAGE software.
The file CrohnsMeta.xml provides a StatDataML description of the data set.
