OMIA:000975-9940 : Tail, short in Ovis aries |
In other species: dog , cattle , domestic cat , Asiatic golden cat
Categories: Limbs / digit / tail phene
Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 601397 (gene) , 615709 (trait) , 182940 (trait)
Links to MONDO diseases: No links.
Mendelian trait/disorder: unknown
Considered a defect: yes
Cross-species summary: Also called brachyury
Species-specific description: There is hope that this trait may provide a form of natural resistance to the sheep blowfly.
Molecular basis: Zhi et al. (2018) reported that "a nonsynonymous mutation at c.G334T [in the TBXT gene, previously known as the T gene] resulted in p.G112W substitution." These authors "inferred that the c.G334T mutation in T leads to functional changes in Brachyury—encoded by this gene—resulting in the short-tail phenotype" in the Hulunbuir short‐tailed breed.
Han et al. (2019) reported that "one missense mutation, c.334G>T (GGG>TGG) [which appears to be the same variant reported by Zhi et al. (2018)] with a completely linked [adjacent] synonymous variant c.333G>C (CCG>CCC) [both in the TBXT gene, previously known as the T gene] was found to be associated with the ‘tailless’ characteristic in typical fat‐rumped sheep breeds".
In neither paper do the authors appear to be concluding that the named variants should be listed as likely causal variants.
