defects and prenatal diagnosis Upon completion of this chapter, the student will: Understand the uses and limitations of noninvasive prenatal maternal blood screening for birth defects Be knowledgeable regarding the indications for, and limitations of, first- and second-trimester evaluation of birth defects using the techniques of ultrasound, fetal MRI and ECG Be aware of techniques of amniocentesis and chorionic villus sampling to determine when these invasive diagnostic tests may be indicated Be familiar with alternative reproductive techniques (IVF) and understand when couples might benefit from such technologies Learn about new noninvasive prenatal diagnosis technologies being explored Understand the psychosocial needs of families who are at risk, Birth defects and prenatal diagnosis 3% of births result in a child with a birth defect or genetic disorder Circumstances can increase risk Most affected newborns are born to couples unaware they are at risk and have no family history, Birth Defects and Prenatal Diagnosis Noninvasive prenatal maternal blood screening First-semester evaluation of birth defects Ultrasonogram Fetal magnetic resonance imaging Echocardiography Second-trimester evaluation of birth defects Invasive diagnostic tests Amniocentesis Chorionic villus sampling Alternative reproductive techniques In vitro fertilization Psychosocial needs of families at risk for having children with genetic disorders or birth defects, Prenatal diagnosis and screening Gives parents opportunity to gain information about fetus Gives parents opportunity to examine a range of family planning options Screening can occur before pregnancy or during pregnancy, Genetic Assessment 20,000 genetic disorders have been identified Genetic testing available for 2,000 genetic disorders Ethnic background Specific ethnic backgrounds have higher chance of certain gene mutations associated with genetic disorders Review of medical and pregnancy

First Trimester Ultrasound Establishes viability Determines number of fetuses Confirm placenta position 11 14 weeks can measure nuchal translucency (transparency of the fluid-filled cavity at the nape of the fetuss neck Increased nuchal translucency is associated with adverse outcomes Congenital heart disease Fetal anomalies Fetal death Down syndrome: abnormal Doppler flow in ductus venosus and tricuspid regurgitation (signs of congenital heart disease) Maternal serum (blood) screening Screening for disorders common in specific ethnic groups Cystic fibrosis Sickle cell anemia Tay Sachs Chorionic villus sampling, Screening evaluations during pregnancy First-Trimester Maternal serum screening Free beta hCG and PAPP-A at 10 14 weeks combined with ultrasound identifies 87% fetuses with Down syndrom <5% false-positive Extreme variations of free beta hCG and PAPP-A can indicate: Low birth weight Stillbirth Fetal loss Early delivery Cell-free DNA in plasma of pregnant woman Fetal DNA can be detected in background of maternal DNA, assessment fetal chromosomal abnormalities Further work needs to be done before technique is widely available for clinical use, Screening evaluations during pregnancy First trimester Chorionic villus sampling Performed 10 12 weeks Use ultrasound to guide suction through small catheter passed through cervix or aspiration via needle inserted through abdominal wall and uterus Minute biopsy of chorion (outermost membrane surrounding embryo) Consists of rapidly dividing cells Detects chromosomal abnormalities Use for enzyme assay for inborn errors of metablism Use for molecular DNA analysis to identify specific mutations that cause genetic diseases Does not detect neural tube defects such as spina bifida Safest invasive prenatal diagnostic procedure 1% risk of precedure-related pregnancy loss If performed after 10 weeks, no increased risk of causing fetal anomaly, Screening evaluations during pregnancy Second Trimester Maternal serum screening Screening sensitivity is improving but is not diagnostic AFP (low), hCG, uE3, and Inhibin A has improved detection of Down syndrome, 80% with 5% false-positive rate When combined with other indicators including maternal age, weight, race, diabetic status and number of fetuses, can assess risk for: Neural tube defects (spina bifida and anencephaly) Abdominal wall defects (gastroschisis and omphalocele) Trisomy 18 AFP high levels can be associated with multiple fetuses, gestational age greater than anticipated or higher risk for preterm delivery, stillbirth, or intrauterine loss If serum screen suggests increased risk for Down syndrome, trisomy 18 or trisomy 13, diagnostic testing is recommended, Screening Evaluations During pregnancy Second-trimester Ultrasound 18 20 weeks detects 60% of major structural anomalies Can be used to diagnose neural tube defects and abdominal wall defects (previously screened for by second-trimester serum testing) High resolution ultrasound revolutionized identification of fetal anatomic abnormalities Can be used to diagnose: Facial clefts Renal anomalies Skeletal anomalies Hydrocephalus Heart defects Other malformations Does not replace amniocentesis and CVS, Screening evaluations during pregnancy Second trimester Amniocentesis Performed at 15 18 weeks Ultrasound used to guide procedure Needle inserted below mothers umbilicus, through abdominal and uterine walls 1 2 ounces of amniotic fluid aspirated Fetal urine replaces fluid in 24 hours Pregnancy loss when performed before 14 weeks increases, higher rates of musculoskeletal deformities (club foot), and greater risk of fluid leakage CVS preferred first trimester, Screening evaluations during pregnancy Magnetic resonance imaging Used approximately 17 weeks No sedation No known risks at this time MRI of central nervous system can demonstrate presence: Corpus callosum Chiari malformation of the brain Cause of enlarged ventricles (hydrocephalus) Ultrasound

Echocardiography Congenital heart disease (CHD) most common anatomical abnormality, contributing to 1/3 of congenital anomaly deaths in childhood Targeted ultrasound performed 18 22 weeks Three- and four-dimensional studies 10 15% of infants with CHD have underlying chromosomal abnormality, Diagnostic testing of fetal cells CVS Amniocentesis To test for chromosomal analysis Biochemical analysis For inborn errors of metabolism or DNA analysis For fragile X syndrome or cystic fibrosis Fluorescent in situ hybridization (FISH) Short pieces of DNA (called DNA probe) of known sequence can attach to a unique region on a chromosome FISH used to identify specific chromosomes or indicate small deletions of a defined region of a specific chromosome FISH used to detect microdeletions Discover of certain CHDs should prompt consideration of FISH analysis to detect 22q11.2 deletion associated with VCFS/DiGeorge Syndrome, 1 in 4,000 live births, The most sophisticated prenatal diagnostic
