Clinical characteristics of the Norwegian myasthenia gravis study cohort (n = 369).

EOMG = early onset MG; LOMG = late onset MG; AChR-ab+  =  acetylcholine receptor-antibody positive.</p

Conditional analyses of the HLA-A, -B, -C and DRB1 loci (p-values) in early onset myasthenia gravis (EOMG).

<p>P-values are not corrected, p<0.01 is considered significant after correction for multiple comparisons (n = 4).</p

Schematic overview of associated HLA alleles in MG.

<p>The HLA complex on chromosome 6 with its division into three classes. Some key genes and their order on the chromosome are given. Associated HLA alleles reported earlier in Caucasian MG patients (see text for complete references) are illustrated together with the results from the present study.</p

Assessment of the strongest association on the HLA-B*08-DRB1*03:01 haplotype in early onset myasthenia gravis (EOMG).

<p>+  =  positives, −  =  negatives.</p

The most strongly associated HLA alleles in early onset myasthenia gravis (EOMG).

<p>Odds Ratio (OR) and 95% confidence interval (CI) are shown for nominal p-values.</p

Associated alleles in late onset myasthenia gravis (LOMG).

<p>Odds Ratio (OR) and 95% confidence interval (CI) are shown for nominal p-values.</p
