Average Single Telomere Lengths in kb: Mean ± Std (number of telomeres).

End telomere loss: Events where some molecules in a specific sample have demonstrated lack of telomere-like signal at the end of chromosome. Some of these events manifest as additional internal telomere like sequences with blight label while some did not have any ITS.

ITS loss: Events where ITS signal loss is observed.

Total Telomere loss: This is defined as the total number of molecules where either loss of end telomeres signal is observed or loss of ITS signal is observed.

a

End telomere length.

b

Includes both ends and recombined ends.

c

Total telomere loss (end telomere loss, ITS loss).

d

Total telomere less than 500bp (end telomere<500bp, ITS<500bp) (% of total telomeres).
