De novo t(X;21)(q28;q11) in a girl with phenotypic features of Williams-Beuren syndrome.

abstract：:Various heteromorphisms of the 9q heterochromatic area have been reported. In most instances, the extra G positive band is accompanied by an extra C band. We describe a family where the extra G band is totally euchromatic and does not include an extra C band. It is not clear whether these two types of variant chromoso...

abstract：BACKGROUND:Progeroid syndromes are genetic disorders that recapitulate some phenotypes of physiological ageing. Classical progerias, such as Hutchinson-Gilford progeria syndrome (HGPS), are generally caused by mutations in LMNA leading to accumulation of the toxic protein progerin and consequently, to nuclear envelope ...
