Investigation of the Genetics of Hematologic Diseases

Description

Participants will be individuals (proband) receiving therapy or expert consultation regarding a non-malignant hematologic disorder. We propose to use genomics, transcriptomics, proteomics and metabolomic analysis coupled with family linkage studies to identify causal mutations in individuals with undefined hematologic disorders and to characterize genetic modifiers of defined monogenic blood diseases.

A detailed medical history will be obtained, including demographic information for each proband. For each identified biologically related family member, a medical history questionnaire will be obtained. The family history and pedigree will be reviewed in conjunction with a geneticist/genetic counselor. The implications of genetic testing will be explained. If participants consent for future contact, this will take place annually for updates on medical and family history.

All probands will provide peripheral blood samples, and probands who are undergoing a bone marrow aspirate/biopsy for clinical purposes will provide additional aspirates. Biological family members will provide peripheral blood samples as a source for DNA.
