• Heart defects, such as missing or misshaped valves.
• Abnormal limbs, such as a clubfoot.
• Neural tube defects, such as spina bifida, and problems related to the growth and development of the brain and spinal cord.

What are the 3 types of Down syndrome?

There are three types of Down syndrome:

• Trisomy 21. This is by far the most common type, where every cell in the body has three copies of chromosome 21 instead of two.
• Translocation Down syndrome. In this type, each cell has part of an extra chromosome 21, or an entirely extra one.
• Mosaic Down syndrome.
