Intrachromosomal insertion mimicking a pericentric inversion: Molecular cytogenetic characterization of a three break rearrangement of chromosome 20

Abstract excerpt

Intrachromosomal insertions are uncommon rearrangements, in which a chromosomal segment is intercalated into another part of the same chromosome. The insertion may occur in the same arm (paracentric) or in the other arm (pericentric). The cytogenetic recognition of these structurally rearranged chromosomes can be difficult, and intrachromosomal insertions can be easily mistaken for inversions. We describe a case...
