Data are percentage of patients in the diagnostic group who had telomeres less than 1st percentile (<1%), or between 1st and 10th percentile (1-10%). Telomeres that were normal or longer than normal (ie, 10th percentile or above) are not included.
The important groups for this study: DC patients, DC relatives, and all non-DC patients.
FA includes 1 patient after bone marrow transplant whose telomeres were normal, and 3 with hematopoietic somatic mosaicism.
