We construct operators t(z) in the elliptic algebra Aq,p(ŝl(2)c). They close an exchange algebra when pm = qc+2 for m ∈ Z. In addition they commute when p = q2k for k integer non-zero, and they belong to the center of Aq,p(ŝl(2)c) when k is odd. The Poisson structures obtained for t(z) in these classical limits are identical to the q-deformed Virasoro Poisson algebra, characterizing the exchang...

A family is reported in which several members have the Cornelia de Lange syndrome and other members show facial dysmorphism and other features reminiscent of this syndrome. The segregation pattern is consistent with the view that the dysmorphic features (variable) are the manifestation of a single gene in heterozygous form. Chromosome abnormality was not found.

The Revista do Instituto de Medicina Tropical de São Paulo has the honor to present this special issue of the year 2015 that is entirely dedicated to celebrate the centennial anniversary of Prof. Carlos da Silva Lacaz, founder of the Instituto de Medicina Tropical. Simultaneously to the creation of the Institute, the Revista do Instituto de Medicina Tropical de São Paulo also began to operate i...

A pair of female monozygotic twins, one of them affected by the de Lange syndrome is described for the first time. Monozygosity was established by most of the accepted standards in use at the present time. Speculation is offered as to whether the discordance in the manifestation of the syndrome provides any clues for understanding its controversial pathogenesis. In this regard two genetic mecha...

Clinical features are variable in patients with Cornelia de Lange syndrome (CdLS). Milder forms exist with structural maintenance of chromosomes 3 (SMC3) mutations. Inherited milder forms of CdLS are uncommon and may be missed if genetic testing is limited to Nipped-B-like protein (NIPBL) and SMC1A. Parental studies should be pursued if there is a history of learning disabilities and/or dysmorp...
