Exploring periodontitis in patients with Chédiak-Higashi syndrome

A study explores the relationship between Chédiak-Higashi syndrome and periodontitis, revealing that LYST mutations affect TLRs and lead to a dysregulated immune response. Classic CHS patients with bone marrow transplantation exhibited mild chronic periodontitis, while atypical CHS patients showed no evidence of aggressive periodontitis.
