Overview of repeats

Repeat lengths over eight GCG repeats have been associated with increased susceptibility to amyotrophic lateral sclerosis (ALS) and the repeat size seemed to be limited to the addition of one or two GCG repeats (Tazelaar et al., 2019). In a healthy population the repeat region comprises of 8 repeats for 72% of individuals and 7 repeats for 25% of them (Tazelaar et al., 2019). Shorter and longer stretches (6, 9, 10) have also been reported in healthy individuals with a very low frequency (Chai et al., 2003).
