Folate deficiency‚ for example‚ appears to play a role in various malformations of the neural tube‚ but the cumulative causes of such malformations and their relative contribution are rather complex. Neural tube defects have also been linked to trisomy 18‚ numerous mutations in the genes necessary for the development of the nervous system‚ and exposure to certain epilepsy drugs. Of the different forms of neural tube defects‚ a condition known as anencephaly is arguably the most severe. Anencephalic

characteristics. In Down syndrome a mistake during division of the sperm or egg cell produces a cell with an extra chromosome 21. This event occurs during cell division and is referred to as nondisjunction‚ or the failure of all chromosomes to separately properly resulting in retention of one of the chromosomes in one of the two new daughter cells. This is also called trisomy 21 and is accounted for 95% of all Down syndrome patients. A rare number of Down syndrome cases the original egg and sperm cells

NORMAL LEVEL-TWO ULTRASOUND SCAN Ultrasound examination during should include a systematic evaluation of fetal anatomy. Apart from anencephaly‚ the fetal organs cannot be accurately measured before 17-18 weeks of gestation. After 30-35 weeks‚ evaluation becomes increasingly difficult. Hence level-two ultrasound scan is done at 18 to 20 weeks of gestation. CLASSIFICATION OF FETAL SONOGRAPHIC EXAMINATIONS 1. First-Trimester Ultrasound 2. Standard Second- or Third-Trimester Ultrasound

DOWN SYNDROME Down Syndrome is a congenital disorder arising from a chromosome It comes from a defect involving chromosome 21. The condition leads to impairments in both cognitive ability and physical growth that range from mild to moderate developmental disabilities. Through a series of screenings and tests‚ Down syndrome can be detected before and after a baby is born. The only factor known to affect the probability of having a baby with Down syndrome is maternal age. Less than one in 1‚000

Non-Disjunction Causes and Effects Overview This paper shows the basis of non-disjunction of chromosome‚ a failure of chromosomes to separate properly during cell division. It emphasizes particularly on how the reproductive cells or gametes is created during reproduction. The gametes of women are eggs and of men are sperms. When the egg and the sperm combine during fertilization at conception‚ they create a normal offspring with the proper number of chromosomes of 46. Nondisjunction occurs when
