title: Prenatal and postnatal diagnosis of Menkes disease, an inherited disorder of copper metabolism.
abstract: 105 patients with Menkes disease have been diagnosed from 64Cu-uptake studies in fibroblasts. These results are presented together with chase results following removal of 64Cu from the medium for 16 Menkes patients. Second-trimester prenatal diagnosis has been performed in 80 pregnancies with male karyotype. These 64Cu-uptake results show some overlap between the upper end of the normal range and the lower end of the Menkes range. Results are presented to show that a combination of 64Cu-uptake and chase results offers a better diagnostic potential than 64Cu-uptake per se. Chorionic villus copper values from 53 first-trimester prenatal diagnoses are presented. Maternal deciduum from some of these pregnancies contain similar high amounts of copper as found in the chorionic villus samples from affected fetuses. 64Cu-uptake in cultured chorionic villi from affected fetuses and unaffected fetuses is not discriminatory. Chase results seem however to offer a better diagnostic potential.
