A multistage testing strategy for detection of quantitative trait Loci affecting disease resistance in Atlantic salmon.
A multistage testing strategy to detect QTL for resistance to infectious salmon anemia (ISA) in Atlantic salmon is proposed. First, genotyping of amplified fragment length polymorphisms (AFLP) and a transmission disequilibrium test (TDT) were carried out using dead offspring from a disease resistance challenge test. Se...

Ordered subset linkage analysis supports a susceptibility locus for age-related macular degeneration on chromosome 16p12.
Age-related macular degeneration (AMD) is a complex disorder that is responsible for the majority of central vision loss in older adults living in developed countries. Phenotypic and genetic heterogeneity complicate the analysis of genome-wide scans for AMD susceptibility loci. The ordered subset analysis (OSA) method ...

Fanconi anaemia and leukaemia - clinical and molecular aspects.
Fanconi anaemia (FA) is an autosomal recessive chromosomal instability disorder, which is characterized by congenital abnormalities, defective haemopoiesis and a high risk of developing acute myeloid leukaemia and certain solid tumours. It can be caused by mutations in at least eight different genes. Molecular studies ...

How should preconceptional cystic fibrosis carrier screening be provided? Opinions of potential providers and the target population.
Since the identification of the cystic fibrosis (CF) gene, large-scale CF carrier screening has become possible. One possible target group is couples planning a pregnancy (preconceptional screening), providing a maximum number of reproductive options and a minimum of time constraints.</AbstractText>To identify obstacle...

Mucolipidosis type IV a rare genetic disorder: new addition to the Ashkenazi Jewish panel.
Mucolipidosis type IV (MLIV) is a rare genetic disorder that primarily affects persons of Ashkenazi Jewish descent. Current information available about testing options and the Ashkenazi Jewish Screening panel, including the addition of screening for MLIV, is presented. The importance of genetic screening and counseling...

Development of the AmpFISTR SEfiler PCR amplification kit: a new multiplex containing the highly discriminating ACTBP2 (SE33) locus.
The AmpFISTR SEfiler kit co-amplifies 11 short tandem repeat loci including SE33 in a single multiplex. After establishing the optimum in primer titration studies, the primer concentrations of all loci in the multiplex were chosen such that the heterozygote peak height ratios of each of the loci were balanced. The comb...

Single nucleotide polymorphisms of protein tyrosine phosphatase 1B gene are associated with obesity in morbidly obese French subjects.
<AbstractText Label="AIMS/HYPOTHESIS" NlmCategory="OBJECTIVE">The development of insulin resistance may contribute to the occurrence and progression of the metabolic syndrome associated with obesity. Components contributing to the insulin pathway and its regulation are good candidates for the molecular study of metabol...

Partial trisomy 13 with features similar to C syndrome.
We report a case of partial trisomy 13 with trigonocephaly, upslant eyes, long smooth philtrum, polydactyly, agenesis of right kidney and mild developmental delay. In this family phenotypically normal mother had pericentric inversion of chromosome 13 and the child (proband) received recombinant 13 from the mother. Gene...

Methodology in longitudinal studies on psychological effects of predictive DNA testing: a review.
In the last two decades predictive testing programs have become available for various hereditary diseases, often accompanied by follow-up studies on the psychological effects of test outcomes. The aim of this systematic literature review is to describe and evaluate the statistical methods that were used in these follow...

Germline E-cadherin mutations in hereditary diffuse gastric cancer: assessment of 42 new families and review of genetic screening criteria.
Mutations in the E-cadherin (CDH1) gene are a well documented cause of hereditary diffuse gastric cancer (HDGC). Development of evidence based guidelines for CDH1 screening for HDGC have been complicated by its rarity, variable penetrance, and lack of founder mutations.</AbstractText>Forty three new gastric cancer (GC)...

Analysis of missense variation in human BRCA1 in the context of interspecific sequence variation.
Interpretation of results from mutation screening of tumour suppressor genes known to harbour high risk susceptibility mutations, such as APC, BRCA1, BRCA2, MLH1, MSH2, TP53, and PTEN, is becoming an increasingly important part of clinical practice. Interpretation of truncating mutations, gene rearrangements, and obvio...

Analysis of European mitochondrial haplogroups with Alzheimer disease risk.
We examined the association of mtDNA variation with Alzheimer disease (AD) risk in Caucasians (989 cases and 328 controls) testing the effect of individual haplogroups and single nucleotide polymorphisms (SNPs). Logistic regression analyses were used to assess risk of haplogroups and SNPs with AD in both main effects a...

Searching for genomic variants in IGF2 and CDKN1C in Silver-Russell syndrome patients.
Silver-Russell syndrome (SRS) is a heterogeneous syndrome with evidence for a substantial role of genetic factors in its etiology. Apart from other specific clinical features, severe intrauterine and postnatal growth retardation are the dominant characteristics of SRS. Therefore, studies on the genetic basis of the dis...
