Thymidine 289-291 5-hydroxytryptamine receptor 2A Homo sapiens 66-83 15037867-4 2004 Another 5-HT(2A) receptor polymorphism consists of the silent thymidine-cytosine substitution (102T>C), which has been controversially associated with schizophrenia. Thymidine 62-71 5-hydroxytryptamine receptor 2A Homo sapiens 8-25
