Counselling following diagnosis of fetal abnormality: a comparison between German, Portuguese and UK geneticists.
The principle of non-directiveness in genetic counselling is embraced by all relevant professional bodies. Little is known about the extent to which it is endorsed by geneticists, or incorporated into their clinical practice. The aim of the current study is to document how geneticists in three European countries, Germa...

Difference in frequencies of the cystic fibrosis alleles, delta F508 and W1282X, between carriers and patients.
One major mutation, delta F508, causing cystic fibrosis (CF) is found in most populations around the world. Among CF patients of Jewish Ashkenazi origin two major mutations, W1282X and delta F508 were found. We compared the relative frequencies of the two major mutations found in this patient population to their relati...

Assignment of granular corneal dystrophy Groenouw type I (CDGG1) to chromosome 5q.
Granular corneal dystrophy Groenouw type I (CDGG1) is an autosomal dominant disease with complete penetrance. 124 blood samples were collected from a single Danish pedigree of seven generations. Linkage was discovered with markers on chromosome 5q, with IL9 (Z = 15.96; theta M = 0.027, theta F = 0.00) and D5S436 (Z = 1...

Transition from normal to premutated alleles in fragile X syndrome results from a multistep process.
In fragile X syndrome, the most common cause of inherited mental retardation, phenotypic expression has been linked to a region containing a repetitive sequence, (CGG)n, that appears to lengthen dramatically in fragile X patients and to show length variation in normal individuals. In order to investigate possible mecha...

Mutations in the muscle sodium channel gene (SCN4A) in 13 French families with hyperkalemic periodic paralysis and paramyotonia congenita: phenotype to genotype correlations and demonstration of the predominance of two mutations.
Hyperkalemic periodic paralysis (hyperPP), paramyotonia congenita (PC) and PC with myotonia permanens are closely related muscle disorders of genetic origin due to allelic mutations in the muscle sodium channel gene, SCN4A. Seven families of French origin with hyperPP were studied. Five of these had the Thr704Met mutat...

Strong founder effect for the fragile X syndrome in Sweden.
We analyzed the FRAXAC2 and DXS548 microsatellites in normal and fragile X chromosomes from Sweden and the Czech Republic in order to investigate a possible founder effect for chromosomes carrying a fragile X mutation. We report a much stronger linkage disequilibrium between the marker haplotypes and the disease in Swe...

DNA diagnostics of the Marfan syndrome: application of amplifiable polymorphic markers.
The diagnosis of Marfan syndrome (MFS) is still based on careful clinical examination. There are, however, many factors creating problems in the firm establishment of the correct diagnosis. After the identification of the defective gene in MFS, fibrillin 1 (FBN1), several mutations in this gene have been reported. Sinc...

Limited expansion of the (CAG)n repeat of the Huntington gene: a premutation (?).
Huntington's disease (HD) is an autosomal dominant disorder with choreic movements, psychiatric manifestations and cognitive dysfunction. Recently the IT15 gene on chromosome 4p has been identified containing an unstable and expanded trinucleotide repeat in patients with HD. We report on the characteristics of this rep...

The 8993 mtDNA mutation: heteroplasmy and clinical presentation in three families.
The point mutation at bp 8993 of human mtDNA in the ATPase 6 gene is associated with neurogenic weakness, ataxia and retinitis pigmentosa, and with subacute necrotizing encephalomyelopathy (Leigh disease) when present at high copy number. In this study we describe three new multiplex families with the ATPase 8993 mtDNA...

A simple method for prenatal diagnosis of trisomy 21 on uncultured amniocytes.
Prenatal diagnosis of trisomy 21 would be easier if fluorescence in situ hybridization (FISH) could be applied to interphase nuclei. Therefore, we prepared a chromosome-21-specific probe by in vitro enzymatic amplification of inter-Alu sequences from YAC clones previously localized to this chromosome. This probe was us...

Screening for carriers of cystic fibrosis among pregnant women: a pilot study.
Cystic fibrosis (CF) is one of the most common hereditary disorders among Caucasians. In such populations a highly prevalent mutation causing CF, delta F508, has been identified. It comprises 88% of Danish CF mutations. This mutation and five others account for 90% of all CF mutations, making carrier screening on a pop...

Collaborative study of the molecular epidemiology of Tay-Sachs disease in Europe.
Tay-Sachs disease is a lipidosis due to the deficiency of the lysosomal hexosaminidase A. In order to understand the molecular mechanisms of this enzyme deficiency we studied 42 patients of different ethnic origins diagnosed in Europe. The strategy used consists in HEXA cDNA amplification followed by allele-specific ol...

A five-year prospective study of the health of children in different ethnic groups, with particular reference to the effect of inbreeding.
A 5-year prospective study of 4,934 children of different ethnic groups has demonstrated a 3-fold increase of postneonatal mortality and childhood morbidity in the offspring of consanguineous Pakistani parents. Most of these families contained more than one consanguineous union, resulting in a mean inbreeding coefficie...

Testing genomic imprinting in Wilm's tumor.
Data from 511 cases of Wilms' tumor in France (including 12 familial cases) and 8 pedigrees from the literature were analyzed to test three modifications of Knudson's classical bimutational theory, based on genomic imprinting in Wilms' tumor carcinogenesis. Analysis of data of age at diagnosis and segregation analysis ...

Striking founder effect for the fragile X syndrome in Finland.
The fragile X mental retardation syndrome is caused by the expansion of an unstable CGG repeat in a 5' exon of the FMR1 gene. Significant linkage disequilibrium between this mutation and flanking microsatellite markers has been observed previously in Caucasian populations, a very unusual finding for an X-linked disease...
