OMIA 000715-9796 : Neuroaxonal dystrophy, generic in Equus caballus
In other species: domestic cat , dog , sheep , rabbit Possibly relevant human trait(s) and/or gene(s) (MIM number): 608507 Mendelian trait/disorder: no Mode of inheritance: Multifactorial Considered a defect: yes Key variant known: no Cross-species summary: Progressive ataxia, hypermetria, proprioceptive deficits, head incoordination and tremors. Species-specific symbol: eNAD Inheritance: From a pedigree analysis, Finno et al. (2013) concluded that this disorder is polygenic with high heritability of 70%. Molecular basis: Transcriptome profiling by Finno et al. (2016) led them to "hypothesize that the protective role of α-TOH [α-tocopherol] in eNAD may reside in its ability to prevent oxysterol accumulation and subsequent activation of the LXR [liver X receptor] in order to decrease lipid peroxidation associated neurodegeneration."
