Abstract:

We present the first case of direct and inverted reciprocal chromosome insertions between human chromosomes 7 and 14, ascertained because of repeated spontaneous abortions. Prometaphase GTG banding analysis showed the karyotype to be 46, XX, inv ins (7;14)(7pter-->7q11.23::14q32.2-->14q 22::7q21.2-->7qter), dir ins(14;7)(14pter-->14q 22::7q11.23-->7q21.2::14q32.2-->14qter). Origins of the insertion have been confirmed by chromosome painting with libraries specific for chromosomes 7 and 14 using fluorescence in situ hybridization.
