AD variants typically occur near the N terminal of the triple helical (TH) domain, which contains a critical region of 10 to 15 Gly-X-Y triplets; in-frame exon-skipping variants and glycine substitutions in this region tend to result in more severe phenotypes

AR variants are usually nonsense or fs, or biallelic variants located near the C-terminal end of the TH domain, where they will be excluded from assembly

COL6A2 accounts for 44-46% of Collagen VI-Related Dystrophies cases
