Genetic Study of Chronic Lymphocytic Leukemia Families

Status unconfirmed

Conditions studied: Leukemia

In brief

The goal of this research is to identify genes that may be related to the risk of developing CLL. Objectives: The objective of this study to investigate possible candidate susceptibility genes for familial chronic lymphocytic leukemia (CLL) by identifying and recruiting high-risk families. Through our ongoing study of familial aggregation in CLL kindreds (protocol 2003-0498 'Genetic Study of Chronic Lymphocytic Leukemia'), we have identified CLL patients who have one or more living or dead relative(s) affected with CLL or other leukemias or lymphomas. We will also identify patients in high-risk families from referrals from leukemia clinicians and from self-referrals from patients who learn about our study from the ClinicalTrials.gov website. We plan to invite probands (patients diagnosed with CLL) and their family members with other leukemias and lymphomas and a sample of unaffected relatives to participate in a genetic/linkage study. We will obtain demographic and clinical information along with specimens (blood or buccal samples) from all participants. These families will be part of the Genetic Epidemiology of CLL Consortium, a multicenter, multidisciplinary consortium, based at the Mayo Clinic Cancer Center under the direction of Susan Slager, PhD. This is funded from NCI through a subcontract with Mayo Clinic. Genotypic data will be analyzed at Mayo Clinic, and coded, de-identified data will be shared with the NIH Genome-Wide Association Studies (GWAS) data repository.

Who can join

Age: any. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Patients with histologically confirmed CLL who have living or dead relatives affected with CLL. They must agree to complete a risk factor questionnaire and a family history questionnaire, and to donate a 50mL blood specimen or a buccal specimen.
• Relatives of the CLL patients who have CLL or other lymphoproliferative disorders (i.e., leukemia \& lymphoma). They must agree to complete a risk factor questionnaire and donate a 50mL blood specimen or a buccal specimen. They will need to sign an authorization to release their medical records so that we can confirm their diagnosis.
• A sample of unaffected relatives of the CLL patients. They must agree to complete a risk factor questionnaire and donate a 50mL blood specimen or a buccal specimen.

You may not qualify if…

• No exclusion criteria
