What medical interventions may be necessary for someone with Edwards' syndrome (trisomy 18)?
Medical interventions for someone with Edwards' syndrome (trisomy 18) may include surgery for heart defects, feeding and breathing support, and pain management.
Can Edwards' syndrome (trisomy 18) be diagnosed after birth?
Yes, Edwards' syndrome (trisomy 18) can often be diagnosed after birth based on physical features and genetic testing.
What is the genetic basis of Edwards' syndrome (trisomy 18)?
Edwards' syndrome (trisomy 18) is caused by the presence of an extra copy of chromosome 18, usually due to a random error in cell division during fetal development.
How is Edwards' syndrome (trisomy 18) managed?
Edwards' syndrome (trisomy 18) is managed through medical interventions and supportive care to manage symptoms and improve quality of life.
What is the incidence of Edwards' syndrome (trisomy 18) in miscarriages and stillbirths?
The incidence of Edwards' syndrome (trisomy 18) may be higher in miscarriages and stillbirths, as these pregnancies are often terminated due to complications from the condition.
What is the prevalence of Edwards' syndrome (trisomy 18) in the general population?
The prevalence of Edwards' syndrome (trisomy 18) in the general population is estimated to be around 1 in 6,000 live births.
