class Ensembl::Variation::Variation

The Variation class represents single nucleotide polymorhisms (SNP) or variations and provides information like the names (IDs), the validation status and the allele information.

BUG: fields like validation_status and consequence_type are created using SET option directly in MySQL. These fields are bad interpreted by ActiveRecord, returning always 0.

This class uses ActiveRecord to access data in the Ensembl database. See the general documentation of the Ensembl module for more information on what this means and what methods are available.

@example

v = Variation.find_by_name('rs10111')
v.alleles.each do |a|
  puts a.allele, a.frequency
end

variations = Variation.fetch_all_by_source('dbSNP') # many records
variations.each do |v|
  puts v.name
end
