Brief Summary
The aim of this project is to identify genetic risk factors associated with familial papillary thyroid carcinoma (PTC). Papillary thyroid cancer is a type of cancer that shows high heritability. However, the specific genetic factors that cause an increased risk have been elusive.

Outcome Measures
Primary Outcomes (1)
Genetic variants associated with familial papillary thyroid cancer as assessed by multiple genetic testing methodologies
Variants will be assessed for segregation within families, expression in the normal thyroid and/or thyroid cancer, and functional significance
Up to 5 years
Eligibility Criteria
Families with at least 4 living individuals with a diagnosis of papillary thyroid carcinoma
You may qualify if:
- Patients with a diagnosis of PTC and a family history of PTC in 3 or more living relatives
- Affected and unaffected family members of the proband\*
- For familial cases (families with 4 or more cases of PTC), participation will be offered to all living family members with PTC or benign thyroid disease as well as selected unaffected first and second degree relatives. Participation may also be offered to spouses when needed for analyzing parent/offspring samples.
You may not qualify if:
- Known germline predisposition (ex: pathogenic PTEN variant)
- Non-English speaking
