Age-related macular degeneration (AMD) is a multifactorial disorder affecting the visual system with a high prevalence among the elderly population but with no effective therapy available at present. To better understand the pathogenesis of this disorder, the identification of the genetic factors and the determination of their contribution to AMD is needed.(More)
BACKGROUND Malignant hyperthermia (MH), linked to the ryanodine receptor 1 gene (RYR1) on chromosome 19, is a potentially lethal pharmacogenetic disorder which may lead to a disturbance of intracellular calcium homeostasis when susceptible individuals are exposed to halogenated anaesthetics, suxamethonium, or both. Central core disease (CCD) is a rare(More)
PTEN: and beta-catenin mutations constitute the predominant genetic alterations in endometrioid carcinomas of the endometrium. PTEN encodes a dual-specificity phosphatase with lipid phosphatase and protein tyrosine phosphatase activities that regulate both apoptosis and interactions with the extracellular matrix. Recent studies have associated PTEN(More)
Increasing attention has been directed toward assessing mutational fallout of stereocilin (STRC), the gene underlying DFNB16. A major challenge is due to a closely linked pseudogene with 99.6% coding sequence identity. In 94 GJB2/GJB6-mutation negative individuals with non-syndromic sensorineural hearing loss (NSHL), we identified two homozygous and six(More)
At the dawn of human genetics Sir Archibald Garrod used alkaptonuria as a paradigm to demonstrate the applicability of the Mendelian laws to men and to develop the concept of inborn errors of metabolism. The human cDNA for homogentisate 1,2 dioxygenase was identified due to its homology to the corresponding mouse enzyme and was screened for mutations in(More)
We have recently characterised the genomic organisation of a novel interphotoreceptor matrix proteoglycan, IMPG1, and have mapped the gene locus to chromosome 6q13-q15 by fluorescence in situ hybridisation. As the interphotoreceptor matrix (IPM) is thought to play a critical role in retinal adhesion and the maintenance of photoreceptor cells, it is(More)
The interphotoreceptor matrix is a unique extracellular matrix occupying the space between the photoreceptors and the retinal pigment epithelium. Due to its putative function in the maintenance and integrity of the photoreceptor cells, it is conceivable that it is involved in retinal degeneration processes. More recently, a novel gene encoding a 150-kDa(More)
The RS1 gene is the causative gene in X-linked juvenile retinoschisis (RS). We have screened this gene for mutations in 13 patients with RS and in 7 probands with senile retinoschisis, a sporadic, later-onset form of retinoschisis. Mutations were detected in all RS patients. Of the 11 different mutations identified, six have been reported previously and(More)
3-(3-Cyclopentyloxy-4-methoxy-benzyl)-8-isopropyl-adenine V11294 (1) has been identified as a lead structure, which selectively inhibits human lung PDE4 (436 nM) and is also active in a number of in vitro and in vivo models of inflammation. Here we describe the synthesis and pharmacology of a series of highly potent 8-[(benzyloxy)methyl]-substituted(More)
