Down's syndrome (DS) is the commonest single cause of severe mental retardation in children. It can be diagnosed antenatally by chorionic villus sampling (CVS) or amniocentesis followed by karyotyping. At one time the sole indication for these invasive procedures was maternal age: typically women above age 35. However, this led to the detection of only

Previous studies have suggested a positive correlation between grand multiparity and the incidence of Down syndrome (DS). In order to study different parities as risk factors for DS, the Swedish health registries were used, and 2,615 infants with Down syndrome were selected from 2,184,590 infants born in 1973-1993.

Among the 500 Down syndrome children karyotyped, 15 (3%) were due to translocation; 10 were 21;21 translocation and five 14;21. There were 9 cases of de novo translocations, while 6 were inherited from father or mother. Family history was characteristic in all the translocation cases, with younger parental age, fetal wastage in the family, recurrence ...

Down’s syndrome is the most well-known chromosomal abnormality. The overall incidence in Caucasian, Japanese and American Negro populations is between one in every 660 live births and one in every 800 live births. These are average figures, as Down’s syndrome is very dependent on the age of the mother.
