New insights in phenotype and treatment of lung disease immuno-deficiency and chromosome breakage syndrome (LICS).

We report five patients with lung disease immuno-deficiency and chromosome breakage syndrome (LICS) but without recurrent infections and severe immunodeficiency. One patient had extended survival to 6.5 years. Hematopoietic stem-cell transplantation failed to cure another patient. Our findings suggest that the immunological abnormalities can be limited and do not fully explain the LICS phenotype. [ABSTRACT FROM AUTHOR]
