ostic technique that amplifies specific dna sequences, allowing for the detection of even a single gene mutation associated with inherited diseases. karyotyping, a genetic test, examines chromosomes under a microscope, identifying abnormalities in structure or number, like trisomy 21 in down syndrome, which affects development. treatment and management strategies enzyme replacement therapy, costing upwards of $200,000 annually, delivers functional enzymes to compensate for genetic deficiencies, mitigating disease symptoms substantially. gene therapy approaches, costing millions per treatment, offer potential cures by inserting functional genes, though long-term effects require 10-15 years of careful observation. thank you for your attention image2.jpg image3.jpg image4.jpg image5.jpg image6.jpg image7.jpg
