Foehn wind there is no precipitation, implies there must be other mechanisms. 2) Isentropic draw-down (the draw-down of warmer, drier air from aloft): When the approaching winds are insufficiently strong to propel the low-level air up and over the mountain barrier, the airflow is said to be 'blocked' by the mountain and only air higher up near mountain-top level is able to pass over and down the lee slopes as foehn winds. These higher source regions provide foehn air that becomes warmer and drier on the leeside after it is compressed with descent due to the increase in pressure towards the surface.
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
