OMIA 000245-9615 : Curly coat in Canis lupus familiaris

In other species: cattle , horse , domestic cat

Possibly relevant human trait(s) and/or gene(s) (MIM number): 608245

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2009

Mapping: By conducting a GWAS on 31 curly-hair and 41 wavy-hair Portugese Water dogs, each genotyped with an Affymetrix Version 2 Canine SNP chip (yielding 56,395 informative SNPs for analysis), Cadieu et al. (2009) highlighted a region on chromosome CFA27.

Molecular basis: Fine-mapping and subsequent sequencing within the candidate region on CFA27 (see Mapping section) enabled Cadieu et al. (2009) to identify the causal mutation as a missense SNP (Arg151Trp) in the KRT71 gene.
