HLA and microtubule-associated protein tau H1 haplotype associations in anti-IgLON5 disease.

ABSTRACT: We investigated the associations with HLA and microtubule-associated protein tau (MAPT) H1 haplotype in anti-IgLON5 disease, a recently identified disorder characterized by gait instability, brainstem dysfunction, and a prominent sleep disorder in association with IgLON5 antibodies and pathologic findings of a novel neuronal-specific tauopathy. We compared the HLA alleles and MAPT H1/H1 genotype of 35 patients with anti-IgLON5 with healthy controls. The on-line server tool NetMHCIIpan 3.1 was used to predict the IgLON5 peptide binding to HLA Class II molecules. The HLA-DRB1*10:01-DQB1*05:01 haplotype was overrepresented in patients with anti-IgLON5 disease (OR = 54.5; 95% CI: 22.2-133.9, p < 0.0001). In addition, HLA-DQA was genotyped in 27 patients, and 25 (92.6%) of them had DQ molecules
