Can you tell me about Down Syndrome?
Can you tell me about Down Syndrome?

Down Syndrome is a genetic condition which can be detected through a simple blood test.  It is caused by a deletion in a chromosome on the 21st pair, which will cause decreased mental capacity, a smaller head size, and learning disabilities.  When I am concerned that a baby has Down Syndrome, I recommend that the parents have a blood test done to confirm, because it’s best to know for sure.

Any other symptoms?
user
Symptoms may be seen early on, including a gap between the pinky and ring fingers, slanted eyes, and a small head.  This may or may not be noted by a doctor at a prenatal checkup.  Down Syndrome can also be identified during the first year of a child’s life, as the child shows physical and mental disabilities that are more apparent as they age.

What do you mean a gap between the pinky and ring fingers?
user
People with Down Syndrome are said to have "mitten deformities", meaning that the ring finger is often larger than the pinky, and the thumb and index finger are often joined.  Many people with Down Syndrome may have a heart murmur, and some will have scoliosis, a spinal curve, or intestinal obstruction, and will have problems with a number of other functions.  In more severe cases, Down Syndrome can cause intellectual disabilities, vision problems, hearing impairments, developmental delays, and various physical disabilities.

Hmm, okay. Does it affect the lifespan?
