Several conditions may cause decreased muscle tone, such as Down syndrome, DiGeorge syndrome, and cerebral palsy.

An ultrasound can detect fluid at the back of a fetus’s neck, which sometimes indicates Down syndrome. The ultrasound test is called measurement of nuchal translucency. During the first trimester, this combined method results in more effective or comparable detection rates than methods used during the second trimester.

Other minorities had lower rates: blacks (18.0), Hispanics (14.4), and Asians (15.8) (12). In comparison, the incidence of major defects was 19.0/1,000 live births among whites.

At what age is Down syndrome diagnosed?
Diagnostic tests that can identify Down syndrome include: Chorionic villus sampling (CVS). In CVS, cells are taken from the placenta and used to analyze the fetal chromosomes. This test is typically performed in the first trimester, between 10 and 13 weeks of pregnancy.
Can father’s age cause Down syndrome?
July 1, 2003 — Older fathers may contribute just as much as older mothers to the dramatic increase in Down syndrome risk faced by babies born to older couples. A new study found that older fathers were responsible for up to 50% of the rise in Down syndrome risk when the mother was also over 40.
