    Primary, congenital neuroaxonal dystrophy with peripheral nerve demyelination in Merino-Border Leicester × Polled Dorset lambs.
    Aust Vet J 2017 Sep 13. Epub 2017 Sep 13.
    DEDJTR Victoria, Animal Health and Welfare, Bendigo, Victoria, Australia.
    Case Report: Clinicopathological features of neuroaxonal dystrophy (NAD) in newborn, Merino-Border Leicester × Polled Dorset lambs are described. The affected lambs were unable to walk at birth and microscopic examination of brainstem and spinal cord sections revealed bilaterally symmetrical accumulations of axonal swellings (spheroids), the histological hallmark of primary NAD. The neurological deficit was also exacerbated by myelin loss and secondary axonal degeneration, particularly in the spinal cord and sciatic nerves, but also, to a more limited extent, in brainstem and spinal nerves.

    Genotype disclosure in the genomics era: roles and responsibilities.
    Aust Vet J 2017 Sep 5;95(9):308-316. Epub 2017 Jul 5.
    Principal Policy Analyst, NSW Department of Premier & Cabinet, Orange, New South Wales 2800, Australia.
    Disclosure of affected breed without disclosure of major progenitors has been the usual practice in scientific papers reporting recessive heritable disorders of cattle. Before molecular genetics, carrier identity could not be used by breeders to control causal mutations because phenotypically normal heterozygotes among genetically related animals could not be detected other than by test mating. Accurate, low-cost DNA tests fundamentally changed this situation. Read More
