Prenatal findings in Brachmann-de Lange syndrome.
Brachmann-de Lange syndrome is a congenital disorder of uncertain cause characterized by severe mental retardation, small stature, microbrachycephaly, hirsutism, limb deformities, and characteristic facies. Although more than 300 neonatal cases have been reported, a lack of specific fetal markers has precluded successful antepartum diagnosis. We describe a case of Brachmann-de Lange syndrome identified at 15 weeks' gestation by a low maternal serum alpha-fetoprotein (MSAFP) value. Sonography revealed a fetus with a posterior nuchal cystic hygroma and early-onset symmetrical intrauterine growth retardation (IUGR). The fetal karyotype was 46,XX, but the infant fulfilled the phenotypic criteria of the Brachmann-de Lange syndrome at delivery. The triad of an abnormally low MSAFP value, early-onset symmetrical IUGR, and characteristic ultrasound findings during the second trimester of pregnancy may define adequate criteria for prenatal diagnosis of Brachmann-de Lange syndrome.
