"Genetics of rheumatoid arthritis'' describes details or minutia of a disease that is highly prevalent across the globe. This book has been prepared based on worldwide research carried out to explore the genetic basis of Rheumatoid Arthritis (RA), a multifactorial and multigenic disease. It uses original experimental work to identify contribution of a candidate gene that causes onset of RA. It is the account of methodologies and results relevant to this specific discipline. The author has tried to put her best academic knowledge and dedicated practical approaches to make the theme of this book understandable for the impending geneticists and Rheumatologists. The book is distinguished from the existing book in the way of narration, even very difficult terms and experiments are described in such a precise way that the researchers and the students would feel ease in reading and practicing. These procedures can easily be selected for developing Standard Operating Procedure (SOPs) fordisease gene association studies. The entire text of the book is also justified by providing rational references.
