Genetic background of gynecological diseases

Rare gynecological diseases with genetic origin


Hyperinsulinemia

Hyperinsulinemia in PCOS has been demonstrated to stimulate ovarian androgen production. Research by Moghetti et al. has shown that insulin increases both adrenal androgen production and adrenal sensitivity to ACTH. The demonstration of insulin resistance is not part of the diagnostic set of criteria for PCOS, but it is detectable in a significant proportion (50-70%) of patients, suggesting a pathological role. The insulin resistance observed in PCOS is tissue specific: while adipose tissue and skeletal muscle become insulin resistant, certain organs (ovaries, adrenal glands, liver) retain their sensitivity to insulin. In contrast to non-insulin-dependent diabetes mellitus, where the molecular mechanisms of insulin resistance can be diverse, an intrinsic genetic disorder independent of the development of NIDDM has been identified as the underlying cause of insulin resistance in PCOS. This disorder results in serine phosphorylation of the insulin receptor (IR) encoded by the INSR (Insulin Receptor) gene and the IRS-1 (Insulin Receptor Substrate 1) signaling protein encoded by the IRS1 (Insulin Receptor Substrate 1) gene, and inhibition of signal transduction, causing insulin resistance and consequently hyperinsulinemia. Serine phosphorylation of the insulin receptor has been identified in 50% of women with PCOS, and variants in its gene have also been associated with the occurrence of PCOS.

Our book was written with the intention of filling a gap. It is the work of specialists - university lecturers, researchers, clinicians - who come across the described symptoms in their daily practice.

Many previously published publications deal with the gynecological pathologies discussed in the volume, but from the perspective of genetics as an etiological factor, focusing on the genetic background of pathological conditions and women's diseases, no book has yet been published. Nowadays, science is developing rapidly, and almost all diseases are subjected to genetic testing during research. For this reason, only those pathologies will be presented for which the tests so far have clearly confirmed the genetic background, that is, those pathologies for which the possibility of a genetic cause has arisen, but cannot yet be clearly proven, do not form the material of the book.

We recommend the book primarily to health professionals, geneticists, obstetricians and gynecologists, pedoatric gynecologists, and pediatricians, and those preparing for special exams. Medical students and midwifery students interested in the topic can find important information in it, and it can also be useful for "non-specialists".
