Power lines and ionizing radiation.

The magnetic field and ionizing radiation dose rate were measured near ground level in the vicinity of a utility power line. The dose rate was monitored using thermoluminescence detectors. Measurements were made at distances up to about 100 m from the main transmission line from the Kewaunee Nuclear Power Plant while the plant was in operation and while the plant was shut down for refueling. No evidence was found that the dose rate is significantly different in the presence of the magnetic field from the power line than in its absence.

Localization of a gene for autosomal dominant Larsen syndrome to chromosome region 3p21.1-14.1 in the proximity of, but distinct from, the COL7A1 locus.

Larsen syndrome (LS) is a skeletal dysplasia (osteochondrodysplasia) in which multiple dislocations of the large joints are the major feature. Nosology in this group of diseases, which constitutes 8% of Mendelian disorders in man, is primarily based on clinical and radiographic features. Hopes for more accurate classification grounds are currently being met by progress in elucidation of underlying genetic defects. We have performed linkage analysis in a large Swedish kindred with autosomal dominant LS and found the gene (LAR1) to be strongly linked to chromosome 3p markers (Zmax = 13.4 at (theta = .00). Recombination analysis indicates that the LAR1 locus is located in a region defined distally by D3S1581 and proximally by D3S1600, which cytogenetically maps to chromosome region 3p21.1-14.1. Linkage and recombination analysis of a COL7A1 PvuII intragenic polymorphism versus LS and chromosome 3 markers indicate that COL7A1 is located close to, but distinct from, the LAR1 locus.
