    We describe a family in which two sisters with the autosomal dominant skeletal dysplasia, Leri-Weill dyschondrosteosis (LWD), developed Hodgkin's disease (HD) in late adolescence. In a preliminary attempt to identify HD susceptibility gene(s), HLA-typing and linkage analysis were carried out in the family. Using HLA molecular typing, both sisters were found to have inherited a variant of the HD-susceptibility allele, DPB1*0301, known as DPB1*2001. Following a previous report of a constitutional chromosome translocation (t(2q;8p)) in a family with LWD, preliminary linkage studies were carried out using chromosome 2q and 8p molecular markers. Regions covered by 7/10 chromosome 2 markers and 4/8 chromosome 8 markers were excluded as the location of a candidate LWD gene. Given the rarity of LWD and HD, their simultaneous occurrence is unlikely to have been due to chance. We suggest that a mutation in the LWD gene itself, or a gene closely linked to it, perhaps acting with increased susceptibility to infection conferred by DPB1*2001, resulted in HD in the two sisters.
