Abstract

Infantile neuronal ceroid lipofuscinosis (INCL, CLN1) is a neurodegenerative disorder in which the biochemical defect is unknown. We earlier assigned the disease locus to chromosome 1p32 in the immediate vicinity of the highly informative HY-TM1 marker by linkage and linkage disequilibrium analysis. Here we report the construction of PFGE maps on the CLN1 region covering a total of 4 Mb of this relatively poorly mapped chromosomal region. We established the order of loci at 1p32 as tel-D1S57-L-myc-HY-TM1-rlf-COL9A2-D1S193-D1S62-D1S211-cen by combining data obtained from analysis of a chromosome 1 somatic cell hybrid panel, PFGE, and interphase FISH. We isolated YACs and constructed two separate YAC contigs, the loci L-myc, HY-TM1, rlf, and COL9A2 being present on a 1000-kb contig and the markers D1S193, D1S62, and D1S211 on a YAC contig spanning a maximum of 860 kb. Within the 1000-kb contig we were able to identify fiveCpG islands in addition to those associated with the earlier cloned genes. The YAC contigs as well as the physical map provide us with tools for the identification of the INCL gene.
