In the original article, there was an error in Conclusion as published.
“TTN c.3092C greater than G (p.Leu6494Arg)” should be changed to “TTN c.19481T greater than G (p.Leu6494Arg)”. The corrected section appears below.
In summary, digenic variants TTN c.19481T greater than G (p.Leu6494Arg) and TRAPPC11 c.3092C greater than G (p.Pro1031Arg) were observed in a LGMD family and co-segregated with the disease phenotype, which may be responsible for the LGMD phenotype. However, our study cannot exclude the missed inspection such as complex rearrangement, gross deletion and gross duplication, as well as deep pathogenic point variants in introns involved in monogenic LGMD, presenting autosomal dominant or pseudo-dominant phenomenon. Our study provides a possibility of a digenic mechanism in unsolved families with muscular dystrophies.
In addition, there was a mistake in the caption for Figure 1 as published. Within the description for Figure 1B, “TTN c.3092C greater than G (p.Leu6494Arg)” should be changed to “TTN c.19481T greater than G (p.Leu6494Arg)”. The corrected caption appears below.
