Following the publication of the original article [1], the authors requested to amend the Abstract and Discussion section as follows:

Abstract

“The HLA allele DRB1*11 was present in 54% of BSS patients, and the majority of them (31%) were positive for *11:03 (vs 1.3% in the general population)”

has been amended to read:

“The HLA allele DRB1*11 was present in 54% of BSS patients, and the majority of them (31%) were positive for *11:03 (vs 1.3% allelic frequency in the general population)”.

Discussion

“Although no HLA allele was shared by the majority of our patients, interestingly, the allele DRB1*11:03 were overrepresented in our cohort (31% vs 1.3% in the general population)”

has been amended to read:

“Although no HLA allele was shared by the majority of our patients, interestingly, the allele DRB1*11:03 were overrepresented in our cohort (31% carrier frequency vs 1.3% allelic frequency in the general population)”.

The correction was deemed necessary to prevent possible misinterpretation of data deriving from the bibliography used. The original article has also been updated as above.
