OMIA 001520-9615 : Cone-rod dystrophy 3 in Canis lupus familiaris
In an independent study published just a week after Kropatsch et al. (2010) Goldstein et al (2010) undertook a GWAS on 21 affected and 22 matched control Glen of Imaal Terriers, each genotyped with the Affymetrix Version 2 Canine SNP chip (yielding 60,245 informative SNPs for analysis), Goldstein et al. (2010), highlighting a region on chromosome CFA16 "shared by six SNPs comprising an interval of approximately 4.4 Mb".Molecular basis: Fine mapping and subsequent sequencing enabled Kropatsch et al. (2010) to identify the causal mutation as "a deletion of exons 15 and 16 which alters the reading frame leading to a premature stop codon" in the ADAM9 gene.
A week later came a report of an independent exhaustive evaluation of candidate genes (both comparative positional and positional) that eventually enabled Goldstein et al. (2010) to identify the same causal mutation, namely "a large genomic deletion (over 20 kb) that removed exons 15 and 16 from the ADAM9 transcript, introduced a premature stop, and would remove critical domains from the encoded protein".Breed: Glen of Imaal. Associated gene:

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.
WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
