ABSTRACT
We report the case of a female patient exhibiting multiple congenital malformations including diaphragmatic hernia and heart defect. Cytogenetic studies (including karyotype, FISH and array-CGH) showed a de novo terminal deletion (6.9 Mb) on chromosome 15 in association with a recombinant X chromosome bearing a 9-Mb Xp duplication and a 46-Mb Xq deletion distal to XIST. The recombinant X chromosome was caused by a maternal inv(X)(p22.31q22.3). The X chromosome inactivation pattern was skewed in the patient suggesting a possible inactivation of the recombinant X chromosome. Considering these results, the phenotype was linked to the de novo terminal 15q deletion. These results strengthen the assumption that array-CGH should be applied to each fetus/newborn with multiple congenital malformations.
