Full exon-intron structures are presented for the NIK serine/threonine protein kinase gene and a novel gene termed C17orf1. By in situ hybridisation and radiation hybrid mapping, a cosmid (cDD-Z) that contains regions of both of these genes has been localised between markers D17S800 and D17S791 at chromosome 17q21. The two genes are thus positional candidates for the mutant locus underlying frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17), a disease for which NIK is also a good biological candidate. Using exon-intron maps, a genomic DNA sequencing based mutation screen has been performed for the NIK and C17orf1 genes in a chromosome 17-linked FTDP-17 pedigree. Two silent single-base variations were detected in C17orf1. No alterations were restricted to DNA samples from patients, thus excluding the C17orf1 and NIK genes as likely sites of mutation FTDP-17.
