@drsaidhasbi: Edward's Syndrome, also known as Trisomy 18, is a rare genetic disorder caused by an extra copy of chromosome 18. Causes and Risk Factors: 1. Trisomy 18 (three copies of chromosome 18) 2. Mosaicism (mix of normal and trisomic cells) 3. Translocation (part of chromosome 18 attaches to another chromosome) 4. Advanced maternal age (over 35 years) 5. Family history of chromosomal abnormalities Symptoms: 1. Severe developmental delays 2. Low birth weight 3. Small size 4. Distinctive facial features: - Small head - Prominent forehead - Small jaw - Low-set ears - Small nose 5. Heart defects 6. Kidney abnormalities 7. Intestinal obstruction 8. rocker-bottom feet 9. Clenched fists 10. Seizures Complications: 1. Respiratory problems 2. Cardiac failure 3. Feeding difficulties 4. Increased risk of infections 5. Developmental delays 6. Intellectual disability Diagnosis: 1. Prenatal testing (amniocentesis, chorionic villus sampling) 2. Ultrasound examination 3. Postnatal physical examination 4. Chromosomal analysis (karyotyping) Treatment and Management: 1. Supportive care 2. Surgery for heart defects or other abnormalities 3. Physical therapy 4. Occupational therapy 5. Speech therapy 6. Nutrition support 7. Palliative care Prognosis: 1. Poor survival rate (50% die within first week) 2. Median life expectancy: 2-4 months 3. Few survive beyond 1 year Incidence: 1. Occurs in approximately 1 in 2,500 to 1 in 6,000 births 2. More common in females (3:2 ratio) Genetic Counseling: 1. Risk assessment for future pregnancies 2. Family planning and reproductive options Edward's Syndrome is a complex condition requiring multidisciplinary care. If you or someone you know is affected, consult a healthcare professional or genetic counselor for guidance.
