A molecular basis for familial hypertrophic cardiomyopathy: a beta cardiac myosin heavy chain gene missense mutation
A. A. Geisterfer-Lowrance, S. Kass, G. Tanigawa, H. P. Vosberg, W. McKenna, J. G. Seidman

Clinical recognition that hypertrophic cardiomyopathy (HCM) was genetically determined set the stage for the systematic collection of family data allowing researchers to exploit the rapid developments in what had been termed at the time of this paper, “the new genetics.”...



Toll-like receptor 4 polymorphisms and atherogenesis
S. Kiechl, E. Lorenz, M. Reindl, C. J. Wiedermann, F. Oberhollenzer, E. Bonora, J. Willeit, D. A. Schartz

Studies have highlighted the proatherogenic effect of intravascular inflammation and the role of infectious agents in atherogenesis...



Prospects for whole-genome linkage disequilibrium mapping of common disease genes
L. Kruglyak

Genetic advances have allowed us to make great progress in determining the molecular substrate for a large number of Mendelian diseases...



Genetic isolates: separate but equal?
L. Kruglyak

This article is a leader to a paper presented by Newton Morton’s group (Lonjou C, Collins A, Morton N. Allelic association between marker loci. Proc Natl Acad Sci U S A. 1999;96:1621- 1626)...



Disruption of the sarcoglycan-sarcospan complex in vascular smooth muscle: a novel mechanism for cardiomyopathy and muscular dystrophy
R. Coral-Vazquez, R. D. Cohn, S. A. Moore, J. A. Hill, R. M. Weiss, R. L. Davisson, V. Straub, R. Barresi, D. Bansal, R. F. Hrstka, R. Williamson, K. P. Campbell

One short phrase can sum up the importance of this paper and the message it delivers, “keep an open mind.” Approximately one third of cases of dilated cardiomyopathy (DCM) appear to have a genetic origin...



A calcineurin-dependent transcriptional pathway for cardiac hypertrophy
J. D. Molkentin, J. R. Lu, C. L. Antos, B. Markham, J. Richardson, J. Robbins, S. R. Grant, E. N. Olson

The pathways that link appropriate stimuli to reprogramming of myocyte gene expression patterns, cell growth, and hypertrophy are poorly understood, but such understanding will be critical if we are to develop new methods of countering the myocardial hypertrophic response and decreasing the associated mortality...



A molecular basis for cardiac arrhythmia: HERG mutations cause long QT syndrome
M. E. Curran, I. Splawski, K. W. Timothy, G. M. Vincent, E. D. Green, M. T. Keating

LQTS, the long QT syndrome, is a relatively uncommon disorder (1/10 000), but with terrible consequences for those families segregating the phenotype...



Marfan syndrome caused by a recurrent de novo missense mutation in the fibrillin gene
H. C. Dietz, G. R. Cutting, R. E. Pyeritz, C. L. Maslen, L. Y. Sakai, G. M. Corson, E. G. Puffenberger, A. Hamosh, E. J. Nanthakumar, S. M. Curristin, et al

Marfan syndrome (MS) is a common inherited single-gene disease characterized by ocular, skeletal, and cardiovascular features...



Molecular medicine. The cholesterol quartet
J. L. Goldstein, M. S. Brown

Low-density lipoprotein (LDL) is now unequivocally causally linked to the development of coronary heart disease (CHD), one of the leading causes of death in the Western world...



Myocyte-enriched calcineurin-interacting protein, MCIP1, inhibits cardiac hypertrophy in vivo
B. A. Rothermel, T. A. McKinsey, R. B. Vega, R. L. Nicol, P. Mammen, J. Yang, C. L. Antos, J. M. Shelton, R. Bassel-Duby, E. N. Olson, R. S. Williams

Molkentin et al (see page 55) beautifully described a calcineurin-dependent pathway that led to the induction of a cardiac hypertrophic gene transcriptional program and subsequent myocardial hypertrophy...
