The sequences of three cosmids (90 kilobases) from the Huntington's disease region in chromosome 4p16.3 have been determined. A 30,837 base overlap of DNA sequenced from two individuals was found to contain 72 DNA sequence polymorphisms, an average of 2.3 polymorphisms per kilobase (kb). The assembled 58 kb contig contains 62 Alu repeats, and eleven predicted exons representing at least three expressed genes that encode previously unidentified proteins. Each of these genes is associated with a CpG island. The structure of one of the new genes, hda1-1, has been determined by characterizing cDNAs from a placental library. This gene is expressed in a variety of tissues and may encode a novel housekeeping gene.
