Abstract
Two thyroid hormone regulated genes, the β-subunits of nerve growth factor (NGFB) and thyroid stimulating hormone (TSHB), have been assigned to mouse chromosome 3 and human chromosome 1q22. We have used the techniques of linkage analysis and pulsed field gel electrophoresis to determine the proximity of these two antithetically regulated genes in this conserved linkage group. Four novel restriction fragment length polymorphisms were identified at the human TSHB gene. Two-point linkage analysis between TSHB and NGFB in 46 families, including the Centre d'Etude du Polymorphisme Humain (CEPH) reference panel, demonstrated no recombination (θ = 0.00, Z ̂ = 42.8). Analysis of this region by pulsed field gel electrophoresis showed that the genes for TSHB and NGFB are located less than 310 kb apart in man and 220 kb in the mouse.
