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

About 1000 cycles have involved single gene mutational analysis.1 Mutational analysis requires additional skills beyond karyotyping for aneuploidies‚ including the ability to conduct the mutliplex polymerase chain reaction (PCR) of the gene of interest and related markers. Several new indications for PGD single gene mutational analysis have recently been reported. New uses include PGD

Acid Maltase Deficiency: It is an autosomal recessive disorder‚ in which the defect is in the gene for the acid maltase enzyme‚ which leads to accumulation of glycogen stored in muscles. Glycogen build up‚ weakens the muscles of a patient suffering from this disorder. This may affect respiratory muscles resulting in respiratory failure. It is also known as the Pompe Disease. Although‚ in childhood and adolescence the symptoms show slow progress and are less severe‚ infantile forms cause death within

Multifactorial: characters that have many factors‚ both genetic and environmental‚ collectively influence phenotype. 3. Pleiotropy: when a gene controls multiple phenotypic effects 4. Epistasis: When a gene at one locus alters the phenotypic expression of a gene at a second locus 5. Carrier: a person who is heterozygous for a recessive disease and therefore
