Edwards syndrome, also called trisomy 18, is a genetic disorder associated with the presence of extra material from chromosome 18. The extra material interferes with normal development.[1] This condition is associated with low birth weight; a small, abnormally shaped head; a small jaw; a small mouth; and clenched fists with overlapping fingers. Infants born with Edwards syndrome have mental retardation, heart defects, and organ abnormalities affecting most systems of the body.[2] Fifty percent of infants with this condition do not survive beyond the first week of life. Some children have survived to teenage years, but with serious medical and developmental problems.[1] Approximately 80 percent of newborns affected by this disorder are female.[2]
