trisomy's Usage Examples:

Patau syndrome, also called trisomy 13, is a congenital (present at birth) disorder associated with the presence of an extra copy of chromosome 13.

Parental chromosome analysis should be offered where trisomy 13 is due to an unbalanced translocation.

Called nuchal translucency, the measurement tends to be larger in fetuses with genetic abnormalities such as Down syndrome, trisomy 13, trisomy 18, Turner syndrome, and triploidy.

Patau syndrome is trisomy 13, in which the developing embryo has three copies of chromosome 13.

Examples of such accidents are development of an extra chromosome 18 (trisomy 18) and Down syndrome.

Partial trisomy of the proximal segment of chromosome 13 is much less likely to be fatal and has been associated with a variety of facial features including a large nose, a short upper lip, and a receding jaw.

Where trisomy 18 is caused by an unbalanced chromosomal translocation, chromosomal analysis should be carried out on both parents.

The most well-known trisomy-related disorder is Down syndrome (trisomy 21), in which the developing embryo has an extra copy of chromosome 21.

A condition called trisomy occurs when three, instead of two, copies of a chromosome are present in a developing human embryo.

Patau syndrome is named for Klaus Patau, who reported the syndrome and its association with trisomy in 1960.

Intrauterine lethality of trisomy 21 fetuses with increased nuchal translucency thickness.
