Table 1.
Study breeds and disorders.
Fig 1.
Number of DNA test results per year.
Bar charts showing the number of test results reported to the Kennel Club per year for all disorder/breed combinations, where ‘t’ (as indicated by the red bar) is the year that the mutation was published (as in Table 1) thereby standardising the ‘testing profile’ by commercial availability rather than chronological year.
Fig 2.
Proportion of dogs with a result.
The proportion of Kennel Club registered dogs born per year relative to the year of publication of the mutation (‘t’, as indicated by the red bar) which have a known genotype (either from a test or hereditary status).
Fig 3.
Proportion of all results coming from tests.
The proportion of all known genotypes (‘all results’) for Kennel Club registered dogs born per year relative to the publication of the mutation (‘t’, as indicated by the red bar) coming from results of DNA tests reported to the Kennel Club (rather than ‘hereditary status’).
Fig 4.
Proportion tested affected and carriers born per year.
The proportion of tested Gordon and Irish Setters born per year that tested as carriers and affected. Year ‘t’ for these breeds is 2012.
Table 2.
Genotype frequencies of registered Gordon and Irish Setters with known genotype born per year.
Fig 5.
Mutation frequency calculated from test data only.
Mutant (disorder-causing) allele frequency, f(m), for each disorder/breed per year of birth relative to the year the mutation was published (t) calculated using test results only.
Fig 6.
Mutation frequency calculated from all data.
Mutant (disorder-causing) allele frequency, f(m), for each disorder/breed per year of birth relative to the year the mutation was published (t) calculated using all known genotype data (test results and hereditary status results).
Table 3.
Estimated mutation frequencies pre- and post-test availability.
Table 4.
Decline in mutation frequency of all progeny, and breeding progeny only, compared to parental mutation frequency.
Table 5.
Decline in mutation frequency assuming mutation frequency at pre-test levels among dogs of unknown genotype.
Table 6.
Breed population size, pre-test mutation frequency, test ‘uptake’, and decline in mutation frequency per breed/disease.

Plot of test uptake on breed population size.
Plot and best fit line of test uptake (proportion registered dogs with result at t+4) on breed population size (mean registrations, 2000–17).
