No evidence for an association of AChR beta-subunit gene (CHRNB1) with myasthenia gravis.

Using a polymorphic dinucleotide repeat, we have investigated the contribution of the gene encoding the beta-subunit of the muscle acetylcholine receptor (CHRNB1), the target autoantigen, to the susceptibility to myasthenia gravis (MG). We have combined a case-control study (comparing 143 patients and 162 controls) and a transmission-disequilibrium test bearing on 35 simplex families with heterozygous parents. There was no evidence for an association of CHRNB1 with MG, even after subgrouping patients according to thymus histology, or other clinical criteria. Interestingly however, the shortest four variants of the CHRNB1 microsatellite were seen only in patients with thymus hyperplasia and in none of the control subjects (P < 0.0025).[1]
