Paracentric inversion

In a paracentric inversion, the inverted chromosome segment is located on one side of the centromere (ie, on one chromosome arm). A representation of normal chromosome 15 is shown on the left. An example of a GTG stained chromosome 15 from a patient with a paracentric inversion of the long arm of chromosome 15 between bands q15 and q24 is shown on the right. A normal GTG stained chromosome 15 is shown in the center. The red arrows show the locations on the normal chromosome where breaks occured in the abnormal chromosome (corresponding to the boxed area).
