An Intronic MBTPS2 Variant Results in a Splicing Defect in Horses with Brindle Coat Texture.

ABSTRACT: We investigated a family of horses exhibiting irregular vertical stripes in their hair coat texture along the neck, back, hindquarters, and upper legs. This phenotype is termed "brindle" by horse breeders. We propose the term "brindle 1 (BR1)" for this specific form of brindle. In some BR1 horses, the stripes were also differentially pigmented. Pedigree analyses were suggestive of a monogenic X-chromosomal semidominant mode of inheritance. Haplotype analyses identified a 5 Mb candidate region on chromosome X. Whole genome sequencing of four BR1 and 60 nonbrindle horses identified 61 private variants in the critical interval, none of them located in an exon of an annotated gene. However, one of the private variants was close to an exon/intron boundary in intron 10 of the MBTPS2 gene encodin
