What is some background information about Arachnodactyly?

Long, slender fingers can be normal and not associated with any medical problems. In some cases, however, "spider fingers" can be a sign of an underlying disorder.

What are the causes of Arachnodactyly?

Causes may include:

  • Homocystinuria
  • Marfan syndrome
  • Other rare genetic disorders
When should I contact a medical professional for Arachnodactyly?

Some children are born with arachnodactyly. It may become more evident over time. Talk to your health care provider if your child has long, slender fingers and you are concerned that an underlying condition may exist.

What should I expect during a doctor appointment?

The provider will perform a physical exam. You will be asked questions about the medical history. This includes:

  • When did you first notice the fingers being shaped like this?
  • Is there any family history of early death? Is there any family history of known hereditary disorders?
  • What other symptoms are present? Have you noticed any other unusual things?

Diagnostic tests are most often not necessary unless a hereditary disorder is suspected.
