Defining the disease liability of variants in the cystic fibrosis transmembrane conductance regulator gene

…, H Yu, N Sharma, AS Ramalho, MD Amaral… - Nature …, 2013 - nature.com
Allelic heterogeneity in disease-causing genes presents a substantial challenge to the translation
of genomic variation into clinical practice. Few of the almost 2,000 variants in the cystic …

Progress in therapies for cystic fibrosis

K De Boeck, MD Amaral - The Lancet Respiratory Medicine, 2016 - thelancet.com
Standard follow-up and symptomatic treatment have allowed most patients with cystic fibrosis
to live to young adulthood. However, many patients still die prematurely from respiratory …

CFTR and chaperones: processing and degradation

MD Amaral - Journal of Molecular Neuroscience, 2004 - Springer
The autosomal recessive disease cystic fibrosis (CF) is caused by mutations in the gene
coding for the CF transmembrane conductance regulator (CFTR) protein, a cAMP-activated …

[PDF][PDF] Revertants, low temperature, and correctors reveal the mechanism of F508del-CFTR rescue by VX-809 and suggest multiple agents for full correction

…, J Williams, S Hirst, CM Gomes, MD Amaral - Chemistry & biology, 2013 - cell.com
Cystic fibrosis is mostly caused by the F508del mutation, which impairs CFTR protein from
exiting the endoplasmic reticulum due to misfolding. VX-809 is a small molecule that rescues …

Molecular targeting of CFTR as a therapeutic approach to cystic fibrosis

MD Amaral, K Kunzelmann - Trends in pharmacological sciences, 2007 - cell.com
One of the major challenges facing the pharmaceutical field is the identification of novel, ‘druggable'
targets common to distinct diseases that, despite their clinical diversity, share the …
