Is there another name for down syndrom?

Answer 1

Trisomy 21
That is the scientific name. It is Trisomy 21 because there are 3 of chromosome number 21, instead of 2, and that's what causes Down Syndrome.

Answer 2

It was originally called mongolism, largely because of the mongoloid slant to the eyes. John Langdon Down was the physician who first described it.

The condition was one of the first discovered chromosomal abnormalities. Lejeune noted that there were 47 chromosomes in the karyotype, and that there were three #21 chromosomes. Hence another name, Trisomy 21.

Also it is termed Down Syndrome after its first describer. The term mongolism is not used much these days, and almost never in the scientific literature.

Answer 3

Trisomy 21
