Familial hypomagnesemia with secondary hypocalcemia (OMIM 602014) is an autosomal recessive disease that results in electrolyte abnormalities shortly after birth. Affected individuals show severe hypomagnesemia and hypocalcemia, which lead to seizures and tetany. The disorder has been thought to be caused by a defect in the intestinal absorption of(More)
PURPOSE Whole-genome scan association analysis was carried out to identify genetic variants predictive of lung cancer risk in smokers and to confirm the identified variants in an independent sample. PATIENTS AND METHODS A case-control study was performed using two pools consisting of DNA from 322 German smoking lung cancer patients and 273 healthy smoking(More)
There is strong evidence to suggest that the peroxisome proliferator-activated receptor (PPAR)-gamma, a member of the nuclear receptor family of transcriptional regulators, mediates tumor suppressive activities in a variety of human cancers. Recently, PPARgamma agonists were found to inhibit growth of melanoma cell lines. Here, we tested the possibility(More)
Very recently, BRAF mutations were found in about 2/3 of malignant melanomas and at lower frequencies in other human cancers. The BRAF gene codes for a protein in the mitogen-activated protein kinase (MAPK) pathway. All mutations identified to date are within the kinase domain, with a single missense mutation (V599E) accounting for 80%. We investigated the(More)
Variants in the tumor suppressor gene ARLTS1 (ADP-ribosylation factor-like tumor-suppressor gene 1) have been shown to influence familial cancer risk. Both Cys148Arg and Trp149Stop were associated with an increased risk of familial or high-risk familial breast cancer, respectively. We studied the impact of these gene variants on melanoma risk, investigating(More)
DNA pooling in combination with high-throughput sequencing was done as a part of the Sequenom-Genefinder project. In the pilot study, we tested 83,715 single nucleotide polymorphisms (SNP), located primarily in gene-based regions, to identify polymorphic susceptibility variants for lung cancer. For this pilot study, 369 male cases and 287 controls of both(More)
A 5-year-old boy presented with ocular anomalies including microphthalmos, colobomas of the iris, choroid, and optic nerve head, and strabismus. Magnetic resonance imaging of the head showed multiple bilateral asymmetric high signal intensity foci in the subcortical and periventricular white matter. Genetic counseling disclosed a 47,XXY karyotype.
The aim of this study was to investigate the role of NBS1 in the pathogenesis of malignant melanoma of the skin. To exclude the common 657del5 founder mutation, a total of 376 melanoma patients from Southern Germany were analyzed for sequence alterations in exon 6 of NBS1 by direct sequencing. Analyses revealed one 657del5 mutation and three nonsynonymous(More)
