Hunt for thyroid cancer genes begins in 1,200 families
NCT ID NCT02776969
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to find the genetic changes that make some families more likely to develop papillary thyroid cancer. Researchers will analyze DNA from 1,200 people who either have this cancer and have at least three affected relatives, or are family members of such patients. The goal is to identify specific gene variants linked to inherited risk, which could lead to better screening and understanding of the disease.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * 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. Exclusion Criteria: * Known germline predisposition (ex: pathogenic PTEN variant) * Non-English speaking
