A dataset containing the ancestry categories defined in NHGRI-EBI GWAS
Catalog framework (Table 1, doi:10.1186/s13059-018-1396-2
). Ancestry
categories are assigned to samples with distinct and well-defined patterns of
genetic variation. You will find these categories in the variable
ancestry_category of the following objects: scores,
performance_metrics and sample_sets. Ancestry
categories (ancestry_category) are further clustered into ancestry
classes (ancestry_class).
Format
A data frame with 19 ancestry categories (rows) and 6 columns:
- ancestry_category
Ancestry category.
- ancestry_class
To reduce the complexity associated with the many ancestry categories, some have been merged into higher-level groupings (
ancestry_class). These groupings represent the current breadth of data in the PGS Catalog and are likely to change as more data is added.- ancestry_class_symbol
3-letter code for the
ancestry_classe.g."EUR"or"MAE".- ancestry_class_colour
Hexadecimal colour code associated with ancestry groupings (
ancestry_class). This can be useful when visually communicating about ancestries.- definition
Description of the ancestry category.
- examples
Examples of detailed descriptions of sample ancestries included in the category.
