Single-gene trait/disorder: unknown
Disease-related: no
Species-specific name: Floppy ears versus erect ears; drop ears versus prick ears
Mapping: Jones et al. (2008) conducted an across-breed GWAS on 2,801 dogs from 147 breeds, each genotyped for 674 equally spaced SNPs, plus an additional 862 SNPs located in regions of interest. The results highlighted a region on CFA34, and regions of lower significance on CFA10, 15 and 32. By conducting a mammoth GWAS on "915 dogs representing 80 American Kennel Club (AKC) recognized breeds as well as 83 wild canids that included wolves, jackals, and coyotes and 10 Egyptian shelter dogs", each genotyped with the Affymetrix v2 Canine SNP chip (yielding 60,968 informative SNPs for analysis, based on a novel screening algorithm, MAGIC), Boyco et al. (2010) "found a single region on CFA10 that is likely responsible for the difference in ear type [floppy versus erect]". By conducting an equally mammoth proof-of-principle GWAS on "12 breeds with pricked ears and 15 breeds with dropped ears", with each dog being genotyped with Illumina CanineHD array (yielding 157,393 SNPs for analysis) developed for this study, Vaysse et al. (2011) confirmed the results of Boyco et al. (2011) by highlighting a region between 10.27 and 11.79Mb on chromosome CFA10.
Molecular basis: Chew et al. (2019): "A new possible functional variant in MSRB3 is identified in this study (g. 8038433del>ins). At this locus, the Dingo has a 5-base insertion variant (g. 8038433del>insTTTAT). All Kelpies have a 10 bp insertion at the same locus (g. 8038433del>insTTTATTTTAT)."
