Genetic Mutation Chromosome 18 is copied three times instead of two during fertilization. There is a picture of Chromosome 18 on the opposite page. Genetic Relationship Trisomy 18 is the second most common Autosomal Trisomy before Down syndrome. This syndrome is neither dominant nor recessive, because it is caused by an extra chromosome in a gamete. Epidemiology Trisomy 18 occurs in every ethnicity in the world, but is mostly occurred in females.

Diagnosis Trisomy 18 cannot be diagnosed before birth. It is usually discovered directly after birth immediately, if the baby is not dead, from the symptoms. || Prognosis A large percentage of Trisomy 18 victims die at or before birth. The survivors live with mental and physical complications, such as retardation, small appendages, lip clefs, inability to eat, and small jaws.

Treatment Cases of Trisomy 18 are treaded case-by-case and have different outcomes for each. Interesting Facts Trisomy occurs in one of five thousand births, with less than a 10% chance of survival past the age of one. Edwards Syndrome was named after John H. Edwards, who described Trisomy 18 in 1960. Creative Way of Teaching A creative way of teaching Trisomy 18 would be to create a representation of what occurs during fertilization, and what goes wrong to cause Trisomy 18.
