Abstract Background The Tnfrh1 gene (gene symbol Tnfrsf23) is located near one end of a megabase-scale imprinted region on mouse distal chromosome 7. about 350 kb distant from the nearest known imprinting control element. Within 20 kb of Tnfrh1 is a related gene called Tnfrh2 (Tnfrsf22) These duplicated genes encode putative decoy receptors in the tumor necrosis factor (TNF) receptor ... https://darthomes.shop/product-category/fountains/
