Abstract excerpt
DNA variants in a 31-kb region of the human major histocompatibility complex, encompassing the tumor necrosis factor (TNF) gene cluster, were surveyed by direct sequencing of 283 unrelated individuals from six Chinese populations. A total of 273 polymorphic sites were identified, with nearly half of them novel. We observed an excess of rare variants and negative values of selection tests of the region, implying...
