Pseudoachondroplasia (PSACH) and multiple epiphyseal dysplasia (MED) are relatively common skeletal dysplasias resulting in short-limbed dwarfism, joint pain, and stiffness. PSACH and the largest proportion of autosomal dominant MED (AD-MED) results from mutations in cartilage oligomeric matrix protein (COMP); however, AD-MED is genetically heterogenous and(More)
BACKGROUND In the past 15 years, clinical laboratory science has been transformed by the use of technologies that cross the traditional boundaries between laboratory disciplines. However, during this period, issues of quality have not always been given adequate attention. The European Molecular Genetics Quality Network (EMQN) has developed a novel external(More)
A library of 50,000 recombinants representative of the human X chromosome has been constructed. Human X chromosomes were physically separated using a fluorescence-activated cell sorter. The DNA was purified from the chromosomes, digested to completion with the restriction enzyme EcoRI and cloned into the phage lambda gtWES.lambda B. The X-derived nature of(More)
Fragile X syndrome is the most common inherited form of mental retardation. It is caused by expansion of a trinucleotide (CGG)n repeat sequence in the 5' untranslated region of the FMR1 gene, resulting in promoter hypermethylation and suppression of FMR1 transcription. Additionally, pre-mutation alleles in carrier males and females may result in Fragile X(More)

Twenty-four families with adult onset polycystic kidney disease were typed for markers flanking the PKD1 locus on chromosome 16. The aggregated results gave a significant lod score in favour of linkage to PKD1. Within this group of families two showed unusual features: recombinations, including double recombinations, and, in one family, an unexpectedly high(More)
96 families at risk of having a child with cystic fibrosis have been counselled about prenatal diagnosis by the use of linked DNA probes. Of the first 30 pregnancies 9 children have been born and confirmed to be free from CF, as predicted; 8 pregnancies were terminated (1 of these was found to be miscarrying at time of termination); 12 pregnancies, in which(More)
A particular haplotype defined by probes XV2c, KM19, and CS.7 at the D7S23 locus was found on 90% of chromosomes which carry cystic fibrosis (CF), but on only 11% of normal chromosomes in a UK sample of CF carriers. We show how such data can be used to calculate carrier risks for people with and without a family history of CF, and give examples of clinical(More)
address: " Mapping complex traits-The human and canine genetic systems " Donor cell neoplasms (DCN) are a rare entity, and the vast majority reported are either AML or ALL. We report two new cases (males, aged 25 and 43) that had an allogeneic SCT from female related donors in first CR following an initial diagnosis of AML and ALL and respectively. Both(More)
Keynote address: " Sweet dreams: using genome wide association methods to find genes for diabetes and obesity " Irish Travellers are a nomadic people in whom early marriage, frequent child bearing and consanguinity are cultural norms. They number 22,445, <0.5% of the Irish population, 9.6% of the 1465 patients listed at NCIMD on January 1 st 2007 were(More)
Disclaimer These Guidelines are based, in most cases, on the reports drawn up by the chairs of the disease-based workshops run by EMQN. These workshops are generally convened to address specific technical or interpretative problems identified by the QA scheme. In many cases, the authors have gone to considerable trouble to collate useful data and references(More)
