We analyzed the involvement of chromosome 18 in Niemann-Pick disease type C (NPC), an autosomal recessive cholesterol-processing disorder. Within affected offspring, the chromosome 18 parental contributions were identified by using allele-specific microsatellite markers. Significant linkage of NPC to an 18p genomic marker, D18S40, was indicated by a two-point lod score of 3.84. Analysis of meiotic chromosomal breakpoint patterns among the affected individuals indicated that the NPC gene is pericentromerically localized on human chromosome 18.
