Parazentrische inversion

WebParacentric inversion. An inversion in which the breakpoints occur on one arm of a chromosome. The inverted segment does NOT include the centromere ( the constricted portion of the chromosome). Because paracentric inversions do not change the arm ratio of the chromosome they are difficult to detect on routine chromosome analysis. ... WebHere the inv- inversion occurs on the same arm and centromere is not involved means, it is a paracentric inversion. The present karyotype is of male with the paracentric inversion on the p arm of chromosome 2. 46,XY,inv(2),(p13q24) Pericentric inversion between the p and q arm of the chromosome 2. 46,Y,r(X): Ring chromosome of X in the male.
