A familial pericentric inversion of chromosome 8 analysed with a high resolution chromosome banding technique.

A familial pericentric inversion of chromosome 8 is described. The break points were localized by a high resolution chromosome banding technique and found to be inv(8)(p23.108q12.100). None of the family members had an unbalanced product of the inversion. There were no phenotypical abnormalities in the carriers. The break points and segregation pattern are compared with those of previously reported pericentric inversion of chromosome 8.
