Amniotic fluid acetylcholinesterase and prenatal diagnosis.
Seller MJ, Cole KJ, Fensom AH, Polani PE. Seller MJ, et al. Br J Obstet Gynaecol. 1980 Jun;87(6):501-5. doi: 10.1111/j.1471-0528.1980.tb04586.x. Br J Obstet Gynaecol. 1980. PMID: 7397083
Raised specific acetylcholinesterase (AChE) activity in amniotic fluid was consistently found to be associated with fetal intrauterine death and neural tube defects, but in just under half of the samples from pregnancies with spina bifida, the increase was marginal. …

Laboratory screening and diagnosis of open neural tube defects, 2019 revision: a technical standard of the American College of Medical Genetics and Genomics (ACMG).
Palomaki GE, Bupp C, Gregg AR, Norton ME, Oglesbee D, Best RG; ACMG Biochemical Genetics Subcommittee of the Laboratory Quality Assurance Committee. Palomaki GE, et al. Genet Med. 2020 Mar;22(3):462-474. doi: 10.1038/s41436-019-0681-0. Epub 2019 Nov 8. Genet Med. 2020. PMID: 31700163 Free article.
These defects are caused by incomplete closure of the neural tube at about 4 weeks of pregnancy. Levels of early second-trimester maternal serum (ms) alpha-fetoprotein (AFP) are sufficiently elevated in affected pregnancies to be used as a population-based sc …

Prenatal diagnosis of open and closed spina bifida.
Ghi T, Pilu G, Falco P, Segata M, Carletti A, Cocchi G, Santini D, Bonasoni P, Tani G, Rizzo N. Ghi T, et al. Ultrasound Obstet Gynecol. 2006 Dec;28(7):899-903. doi: 10.1002/uog.3865. Ultrasound Obstet Gynecol. 2006. PMID: 17086581 Free article.
Open spina bifida was always associated with typical alterations of cranial anatomy, including the so-called 'banana' and 'lemon' signs, while in closed spina bifida the cranium was unremarkable. When the data were available, levels of amniotic fluid alpha- …

Neural tube defects: maternal serum screening and prenatal diagnosis.
Crandall BF, Lebherz TB, Freihube R. Crandall BF, et al. Pediatr Clin North Am. 1978 Aug;25(3):619-29. doi: 10.1016/s0031-3955(16)33607-0. Pediatr Clin North Am. 1978. PMID: 80780
Neural tube defects represent some of the most common and serious of the congenital malformations. Although elevation of alpha-fetoprotein in amniotic fluid is not diagnostic, it does indicate an abnormality of the fetus in a very high proportio …

Prenatal diagnosis of Meckel syndrome: case reports and literature review.
Johnson VP, Holzwarth DR. Johnson VP, et al. Am J Med Genet. 1984 Aug;18(4):699-711. doi: 10.1002/ajmg.1320180416. Am J Med Genet. 1984. PMID: 6207728
We report on 2 couples at risk to have Meckel syndrome (MS) offspring. Three pregnancies were monitored by ultrasonography and alpha-fetoprotein (AFP) assay in midtrimester. Of the 2 involving an affected fetus, one was thought to be unaffected. ...The following obs …
