An integrated physical and gene map of human distal chromosome 17q24-proximal 17q25 encompassing multiple disease loci.
Genetic mapping studies suggest that a small interval on human chromosome distal 17q24-proximal 17q25 harbors genes involved in sporadic breast and ovarian tumorigenesis and in the autosomal dominant disorders hereditary neuralgic amyotrophy and tylosis with esophageal cancer. Prior to this study, isolated genomic clones and markers were assigned to this interval but integrated physical maps were not available. We improved resolution by isolating 52 additional clones and developing 24 additional markers. Genomic clones spanning distal 17q24-proximal 17q25 were organized into a contig with two gaps that encompassed 14 existing genetic markers, 8 known genes (GALR2, AANAT, ENVL, SFRS2, SEC14L, DNAH17, API4, and TK1), and 11 previously identified expressed sequence tags. This integrated map provides a foundation for identifying additional candidate genes for the disorders mapped to this interval.
