FISH mapping of a human chromosome 16 constitutional pericentric inversion inv(16)(p13q22) found in a large kindred.
Fluorescence in situ hybridization analysis (FISH) was used to map the constitutional chromosome 16 pericentric inversion breakpoints inv(16)(p13q22) detected in one individual (II-2) from a large kindred [Bianchi et al., 1992: Am J Med Genet 43:791-795]. The breakpoints found in individual II-2 mapped to distinctly different locations than the chromosome 16 pericentric inversion breakpoints commonly acquired in acute nonlymphocytic leukemia. The constitutional pericentric inversion breakpoints also do not map to regions where low abundance repetitive DNA sequences found in bands 16p13 and q22 are located. The results indicate that low abundance, chromosome 16-specific repetitive DNA sequences in bands p13 and q22 are probably not causally related to the inversion that is found in many members of a large kindred [Bianchi et al., 1992].
