We have reported previously a 10% aneuploidy detection rate among 39 cases of fetal neural tube defects (NTD). Subsequently we amassed an additional experience of over 17,000 prenatal diagnosis cases over a 5-year period. During this period 106 cases of NTDs were identified; 44 with anencephaly, 62

✦ Synopsis
We report on two sib fetuses, products of a consanguineous union, who had multiple and apparently unrelated malformations. The first fetus, a female, had trilobed lungs, a single cardiac ventricle, asplenia, situs ambiguus of the liver, and a lumbosacral meningomyelocele. The brain of this fetus was normal. The second fetus, a male, had bilobed lungs, a single cardiac ventricle, situs solitus of the abdominal organs and spleen, and a semilobar holoprosencephaly. The occurrence of these malformations in sibs of different sexes and the parental consanguinity suggest a recessive mutation in a gene responsible for both heterotaxy and midline defects, including holoprosencephaly.

We describe 2 sibs, a male fetus with an unusual lumbar hernia and spina bifida occulta, and a female fetus with a median abdominoschisis. The first fetus had some signs of lumbocostovertebral syndrome (LCVS), which consists of a congenital lumbar hernia and associated abnormalities such as absent o
With respect to the letter by Dr. Seller [1998] concerning our article "Cervical Ribs in Fetuses With Ullrich-Turner syndrome", I should like to respond as follows. The observation of cervical ribs in fetuses with Ullrich-Turner syndrome has, since publication in this journal, been followed up by a
Congenital hydrocephalus and/or open neural tube defect was present in at least one individual of 98 families out of the 2,000 Palestinian Arabic families who have visited the Genetic clinic at the Hadassah Medical Center. In 22 families the brain malformation was part of a syndrome: Meckel syndrome
