Prenatal diagnosis of del(15)(q11q13)

Abstract
A case of del(15)(q11q13) was detected in amniotic fluid cell cultures and confirmed by cordocentesis in a 27‐year‐old woman with a low maternal serum alpha‐fetoprotein level. The fetus was shown to have a short femoral length on ultrasonography. This structural chromosome abnormality associated with the prenatal ultrasonographic findings and the morphological characteristics visualized after termination of pregnancy strongly suggest Prader‐Willi syndrome.
