A rare pulmonary disease induced by SARS-CoV coronavirus infection, with a reported incubation period varying from 2 to 7 days. Patients present flu-like symptoms, including fever, malaise, myalgia, headache, diarrhoea, and rigors. Dry, nonproductive, cough and dyspnea are frequently reported. Severe cases evolve rapidly, progressing to respiratory distress and failure, requiring intensive care. Mortality rate is 10%. The disease appeared in 2002 in southern China, subsequently spreading in 2003 to 26 countries. Reported human-to-human transmission occurred in Toronto (Canada), Hong Kong Special Administrative Region of China, Chinese Taipei, Singapore, and Hanoi (Viet Nam). [from ORDO]

MARCH is an autosomal recessive lethal congenital disorder characterized by severe hydranencephaly with almost complete absence of the cerebral hemispheres, which are replaced by fluid, relative preservation of the posterior fossa structures, and renal dysplasia or agenesis. Affected fetuses either die in utero or shortly after birth, and show arthrogryposis and features consistent with anhydramnios. Histologic examination of residual brain tissue shows multinucleated neurons resulting from impaired cytokinesis (summary by Frosk et al., 2017). [from OMIM]
