Foehn wind environment with strong and gusty winds. Explanations of the foehn warming and drying effect in popular literature or on the web often single out just one causal mechanism (#1 - Condensation and Precipitation - in the below), but there are in fact four known causes (illustrated in the schematic at top right of this page). These mechanisms often act together, with their contributions varying depending on the size and shape of the mountain barrier and on the meteorological conditions, for example the upstream wind speed, temperature and humidity. 1) Condensation and precipitation: When air is forced upwards over elevated terrain,
Atelosteogenesis type I Atelosteogenesis type I Atelosteogenesis type I is a rare autosomal dominant condition. This condition is evident at birth and is associated with a very poor prognosis for the baby. It may be diagnosed antenatally. This condition is caused by mutations in the filamin B (FLNB) gene. This gene is located on the short arm of chromosome 3 (3p14). Filamin B forms part of the actin cytoskeleton. How these mutations produce the clinical picture is not yet clear. This is a rare condition with a prevalence of < 1/10. The total number of cases reported to date is <20. Clinical features
