Which sample type is NOT an allowed sample for MyRisk testing?

Explanation:
MyRisk testing analyzes germline DNA, so it requires constitutional DNA from validated sources. Blood and saliva provide high-quality germline DNA and are standard accepted specimens for this panel. Skin biopsy, on the other hand, yields DNA from skin tissue that is somatic rather than germline and is not validated for this hereditary cancer risk test, so it is not an allowed sample.
