I personally only know of the clubbing of fingers (webbing)
to be in Cystic Fibrosis...I only know that because (2)
of my hubby's cousins have CF.
Sorry I could not be more help. But Ren seems to have givin you
quite a bit of information to scan through.

Skin discoloration - bluish
Clubbing is a thickening of the flesh under the toenails and fingernails. The nail curves downward, similar to the shape of the round part of an upside-down spoon.
Considerations
Clubbing occurs with a wide number of diseases. It is most often found in heart and lung diseases that cause a lower-than-normal amount of oxygen in the blood.
Clubbing may also be due to lung cancer, and diseases of the liver and gastrointestinal tract.
Clubbing may also occur in families. In this case it may not be due to an underlying disease.

Home Care

When to Contact a Medical Professional
If you notice clubbing, call your health care provider.
What to Expect at Your Office Visit
A person with clubbing usually has other symptoms and signs of a specific condition. Diagnosing that condition is based on:
* Family history
* Medical history
* Physical exam that looks at the lungs and chest
Medical history questions may include:
* Do you have any breathing difficulty?
* Does clubbing affect the fingers, toes, or both?
* Is it becoming more noticeable?
* Is the skin ever bluish-colored?
* What other symptoms do you have?
* When did you first notice this?
The following tests may be done:
* Arterial blood gas
* Chest CT scan
* Chest x-ray
* Echocardiogram
* EKG
* Pulmonary function tests
