Ed·wards syn·drome (ed'wărdz sin'drōm) Trisomy in Group E chromosomes (16-18); second in incidence to trisomy 21 (i.e., Down syndrome) in frequency. Findings include mental retardation, congenital heart disease, spina bifida, and esophageal and biliary atresia. Affected patients generally die within 2 years of birth. Edwards’ syndrome a human genetical abnormality in which there are multiple congenital malformations: elongated skull, low-set ears, webbed neck, severe mental retardation. The condition is caused by TRISOMY of chromosome 18 and, like DOWN'S SYNDROME, is related to maternal age; 90% of cases die in the first six months after birth.Edwards, James Hilton, English physician and medical geneticist, 1928–.
