A genetic, physical, and comparative map of rat chromosome 10.

A map of rat Chromosome (Chr) 10 was generated from 21 markers, mostly of conserved structural genes, by linkage analysis and fluorescence in situ hybridization. The study emphasizes the proximal third of the chromosome which, until now, has been relatively devoid of markers. Based on comparative analysis, our data suggest that genes on rat Chr 10 are conserved on mouse Chr 11, 16, 17 and human Chr 16, 5, and 17.

Genetic mapping of the dentinogenesis imperfecta type II locus.

Dentinogenesis imperfecta type II (DGI-II) is an autosomal dominant disorder of dentin formation, which has previously been mapped to chromosome 4q12-21. In the current study, six novel short tandem-repeat polymorphisms (STRPs) have been isolated, five of which show significant evidence of linkage to DGI-II. To determine the order of the STRPs and define the genetic distance between them, nine loci (including polymorphisms for two known genes) were mapped through the CEPH reference pedigrees.

Genetic mapping near the myd locus on mouse chromosome 8.

Myodystrophy (myd), an autosomal recessive mutation of the mouse characterized by progressive weakness and dystrophic muscle histology, maps to the central portion of Chromosome (Chr) 8 (Lane et al. J. Hered 67, 135, 1976).

Microsatellite-based fine mapping of the Van der Woude syndrome locus to an interval of 4.1 cM between D1S245 and D1S414.

Van der Woude syndrome (VWS) is an autosomal dominant craniofacial disorder characterized by lip pits, clefting of the primary or secondary palate, and hypodontia. The gene has been localized, by RFLP-based linkage studies, to region 1q32-41 between D1S65-REN and D1S65-TGFB2. In this study we report the linkage analysis of 15 VWS families, using 18 microsatellite markers.
