Systemic capillary leak syndrome (SCLS) is a rare life-threatening disorder due to profound vascular leak. The trigger and the cause of the disease are currently unknown and there is no specific treatment. Here, we identified a rare heterozygous splice-site variant in the TLN1 gene in a familial SCLS case, suggestive of autosomal dominant inheritance with incomplete penetrance.

Chronic wasting disease (CWD) is a fatal neurodegenerative disease of cervids caused by an infectious misfolded protein (prion). Several members of the Cervidae, including Rocky Mountain elk (Cervus canadensis nelsoni), are susceptible to CWD. There is no evidence of complete genetic resistance to CWD; the M132L polymorphism in the elk prion protein gene influences the incubation period: longest in 132LL, intermediate in 132ML, and shortest in 132MM elk.

Though far less obvious than direct effects (clinical disease or mortality), the indirect influences of pathogens are difficult to estimate but may hold fitness consequences. Here, we disentangle the directional relationships between infection and energetic reserves, evaluating the hypotheses that energetic reserves influence infection status of the host and that infection elicits costs to energetic reserves. Using repeated measures of fat reserves and infection status in individual bighorn sheep () in the Greater Yellowstone Ecosystem, we documented that fat influenced ability to clear pathogens () and infection with respiratory pathogens was costly to fat reserves.

Bighorn sheep (Ovis canadensis) across North America commonly experience population-limiting epizootics of respiratory disease. Although many cases of bighorn sheep pneumonia are polymicrobial, Mycoplasma ovipneumoniae is most frequently associated with all-age mortality events followed by years of low recruitment. Chronic carriage of M.
