Claims

Breed: Bashkir Curly (Horse)
Disorder:
Mode of inheritance: Autosomal dominant
Summary: Morgenthaler et al. (2017): First described by Crow and Sioux Native American tribes as early as 1801 during winter horse counting [Thomas et al., 1989], Curly horses present a variety of coat curl phenotypes associated with diverse degrees of curliness which can range from “minimal” scattered curled hair up to extremely dense “micro curled” permanent coat as observed in certain Missouri Fox Trotter lines.nbsp;
Defect: yes

Gene: Entrez Gene ID 388944862 (no symbol in OMIA GeneSynonym) — OMIA Phene_Gene
OMIA molecular-genetics note: Morgenthaler et al. (2017): "whole-genome sequences were obtained for one heterozygous curly stallion and its straight-haired son. Among the four non-synonymous candidate variants identified and validated in the curly region, only variant g.21891160G>A in the <em>KRT25</em> gene (KRT25:p.R89H) [omia.variant:856] was in perfect agreement with haplotype status in the whole pedigree.
