Telomere length in inherited bone marrow failure syndromes.

ABSTRACT: Telomeres are long DNA repeats and a protein complex at chromosome ends that are essential for genome integrity. Telomeres are very short in patients with dyskeratosis congenita due to germline mutations in telomere biology genes. We compared telomere length in patients with Fanconi anemia, Diamond-Blackfan anemia and Shwachman-Diamond syndrome with telomere length in dyskeratosis congenita. Telomere length was measured in six leukocyte subsets by automated multicolor flow fluorescence in situ hybridization, and age-adjusted using Z-scores (-2.326 = 1(st) percentile) were created. We examined individual data, and used canonical variate analysis for group comparisons and outlier detection. Most dyskeratosis congenita telomere lengths were below the 1(st) percentile, while only 2 Fanconi ane
