X-linked mental retardation: many genes for a complex disorder.

Abstract:

:X-linked mental retardation (XLMR) is a common cause of moderate to severe intellectual disability in males. XLMR is very heterogeneous, and about two-thirds of patients have clinically indistinguishable non-syndromic (NS-XLMR) forms, which has greatly hampered their molecular elucidation. A few years ago, international consortia overcame this impasse by collecting DNA and cell lines from large cohorts of XLMR families, thereby paving the way for the systematic study of the molecular causes of XLMR. Mutations in known genes might already account for 50% of the families with NS-XLMR, and various genes have been pinpointed that seem to be of particular diagnostic importance. Eventually, even therapy of XLMR might become possible, as suggested by the unexpected plasticity of the neuronal wiring in the brain, and the recent successful drug treatment of a fly model for fragile X syndrome.

  • Retinoid receptors in transcriptional regulation.

    abstract::Our understanding of the mechanism of action of retinoids has been greatly expanded by a series of recent findings. First, the three-dimensional structure of the ligand-binding domain of two retinoid receptors has been solved and suggests that ligand binding induces marked allosteric changes. Second, several co-factor...
