Which condition does not typically associate with a finding of thick nuchal translucency?

Thick nuchal translucency is a measurement taken during the first trimester of pregnancy, particularly during an ultrasound, and is often used as a marker for certain chromosomal and structural abnormalities. A finding of increased nuchal translucency is commonly linked with conditions such as Trisomy 21 (Down syndrome), congenital heart defects, and Turner syndrome.

Skeletal dysplasia, on the other hand, primarily refers to a group of disorders characterized by abnormal bone growth and development. These conditions typically do not present with thick nuchal translucency as a routine marker because they have different etiological underpinnings and associated ultrasound findings. While some skeletal dysplasias can be detected through ultrasound, they are often associated with other specific signs rather than increased nuchal translucency. Therefore, it is more accurate to state that skeletal dysplasia does not typically associate with this particular ultrasound finding, making it the correct answer.
