This study is designed to evaluate the genetics involved in the development of lung disease by surveying genes involved in the process of breathing and examining the genes in lung cells of patients with lung disease.
The study will focus on defining the distribution of abnormal genes responsible for processes directly involved in different diseases affecting the lungs of patients and healthy volunteers.
Optional CT Sub-study
The standard CT scan will be compared to the low dose radiation CT scan for the 150 subjects enrolled in the sub-study to assess the variation between the two techniques. Specifically, the quantitative computer aided detection of lung CT abnormalities from LAM can be compared to assess whether low radiation dose CT exams is an alternative to conventional CT to monitor disease
This optional sub-study will be offered to up to 100 adult subjects with lung disease and up to 50 children age 9 and older with CF. Children will not be enrolled in the optional CT sub-study unless they have had a standard CT scan for medical purposes to use in comparison. One additional low dose radiation CT scan of the chest may be done as part of this sub-study when these subjects have their next annual CT scan.

|Study Type :||Observational|

|Official Title:||Role of Genetic Factors in the Pathogenesis of Lung Disease|
|Actual Study Start Date :||September 13, 1996|
Subjects with pulmonary disease or possible pulmonary disease and Relatives
- evaluating the role of hereditary factor [ Time Frame: 1 year ]distribution of genetic variants of nitric oxide synthases and other candidate genes involved in pulmonary function
- low dose radiation CT scan, and Zoom Scan [ Time Frame: on going ]The secondary scan can also be used to obtain a detailed assessment of AML-like tumors and lymphangioleiomyomas in the abdomen or pelvis region when they are detected in the standard chest-abdomen-pelvis CT scan. The enhanced resolution is expected to help classify the tumors without the need for invasive biopsy, for example, by detecting traces of fatty tissue in the tumor to confirm the identity of AML.
