STATUS OF A---T POLYMORPHISM IN EXON II OF KINASE INSERT DOMAIN GENE IN WOMEN WITH PREMATURE OVARIAN FAILURE

Abstract

Ovarian failure is defined as cessation of ovarian function under the age of 40 and it is characterized by amenorrhea hypo estrogenism and elevated gonadotrophin serum levels leading to infertility. Ovarian failure affects 1% of women. Causes of ovarian failure are extremely heterogenous. Ovarian failure is caused either by accelerated loss of eggs or the follicles themselves become less responsive to hormonal stimulation. It is high levels of gonadotrophins (luteinizing hormone and follicle stimulating hormone) hormonal defects may cause severe cardio vascular consequences and leads to the early onset of osteoporosis. Vascular endothelial growth factor (VEGF) is a major growth factor for endothelial cells. VEGF is involved in the process of angiogenesis for the development of Graffian follicle an important feature of growing follicle which has been arrested in the primordial follicular stage .VEGF mediates the process of angiogenesis through its receptors I and II.. Receptor II is known as Kinase insert domain receptor, is a type III receptor tyrosine Kinase.KDR is located at 4q11-q12.The main objective of this study was to screen the mutations in Kinase insert domain by using the techniques DNA isolation, Polymerase chain reaction and restriction fragment length polymorphism.
