Five patients with inv dup(15) chromosomes were investigated with molecular probes on proximal 15q to determine the parental origin and extent of the duplicated segment. Cytogenetic investigation showed that four patients carried one and a fifth patient had two extra chromosomes derived from number 15 in all cells. In situ hybridization with a chromosome 15(More)
In this paper, we present an analysis of the sex chromosomes of four hamster species after application of different staining techniques. The mitotic X chromosomes show a striking similarity in G-banding pattern but rather great differences in their C-banding patterns. A presumably homologous euchromatic segment that exhibits two distinct G-bands appears in(More)
A series of procedures including chromosome microdissection, sequence-independent PCR, Southern-blot-hybrid-selection-cloning and sequencing of microdissected DNA-library members were used to analyze DNA from a familial marker chromosome centromere and to determine the origin of the marker chromosome in the case of a live-born, tetraploid human infant. A(More)
A total of 528 unrelated, apparently healthy, adult and adolescent Austrians (270 females, 258 males, mean age 22.1 years) were examined for lactose absorption capacity employing a noninvasive field test based on breath hydrogen (H2) determination. Subjects exhibiting a change of breath hydrogen concentration of less than 15 volumes per million (vpm) after(More)
Greig cephalopolysyndactyly syndrome (GCPS) is an autosomal dominant disorder that has been mapped to 7p13. We have investigated two patients with GCPS and a cytogenetically visible microdeletion of the short arm of chromosome 7 with gene probes that have been assigned close to the proposed Greig locus. Deletion breakpoints were determined from(More)
To identify by reverse genetics genes on the short arm of human chromosome 7 expected to be involved in the regulation of human craniofacial and limb development, we have set up a human mouse somatic cell hybrid panel that divides 7p into 9 fragments. The breakpoints are defined by deletions or translocations involving one chromosome 7 in the cells of the(More)
Thirteen male newborns of a family spanning five generations revealed a syndrome consisting in elevated birth weight and length, a disproportionately large head with coarse, distinctive facies, short neck, slight obesity, and broad, short hands and feet. The affected who reached adulthood attained heights of about 2 m; their unusual facial and general(More)
Oranizational forms and the current status of genetic counseling within the health care system of 15 European countries were evaluated by questionnaire and at a symposium, with individuals present from Austria, Belgium, Czechoslovakia, Denmark, the Federal Republic of Germany, the German Democratic Republic, Finland, France, Hungary, Italy, the Netherlands,(More)
In order to determine the heterogeneity of mutations in exon 11 of the cystic fibrosis transmembrane conductance regular (CFTR) gene in Austrian cystic fibrosis (CF) patients, we analysed 207 non-delta F508 chromosomes by direct sequencing of PCR-amplified genomic DNA. A total of four previously described point mutations present on 14/207 (6.8%) non-delta(More)
