    Abstract:
    OBJECTIVE: To evaluate the role of homozygosity mapping in the fine mapping of the genes responsible for the rare autosomal recessive diseases. METHODS: Polymerase chain reaction-single sequence length polymorphism was used to genotype the family members from 8 families with osteoporosis-pseudoglioma syndrome(OPS) for 14 polymorphic loci within candidate region. The OPS candidate region was narrowed by searching for homozygous region in affected. RESULTS: The OPS candidate region was narrowed to a 1 cM interval between D11S1296 and D11S4136. CONCLUSION: Homozygosity mapping is a powerful method for mapping and narrowing the candidate region of the genes responsible for the rare autosomal recessive diseases.
