Abstract
We previously identified 18q21.33–q23 as a candidate region in one BP family and constructed a yeast artificial chromosome (YAC) contig map. Here, we mapped eight known CAG/CTG repeats relative to 18q21.33–q23. We also isolated four CAG/CTG repeats from within the region using CAG/CTG YAC fragmentation, one of which is located in the 5′ untranslated region of the CAP2 gene coding for a brain-expressed serine proteinase inhibitor. The triplet repeats located in the 18q21.33–q23 BP candidate region showed no expanded alleles in the linked BP family nor in a BP case-control sample. Moreover, only the CAP2 triplet repeat was polymorphic but no genetic association with BP disorder was observed.
