Chen LS, Tassone F, Sahota P, Hagerman PJ. The (CGG)n repeat element within the 5′ untranslated region of the FMR1 message provides both positive and negative cis effects on in vivo translation of a downstream rep...
متن کاملP-203: Examination of FMR1 Gene Transcription and Protein Expression in Patients with Diminished Ovarian Reserve Reffered to Royan institute
Background: Diminished ovarian reserve (DOR) is a primary infertility disorder characterized by a reduction in the number and/or quality of oocytes, usually accompanied by high follicle-stimulating hormone (FSH) levels and regular menses. DOR aetiology factors are different, such as genetic factors, ageing, autoimmune disorders, adrenal gland impairment factors and iatrogenic causes, e.g. chemo...
متن کاملFragile X-Associated Diminished Ovarian Reserve and Primary Ovarian Insufficiency from Molecular Mechanisms to Clinical Manifestations
Fragile X syndrome (FXS), is caused by a loss-of-function mutation in the FMR1 gene located on the X-chromosome, which leads to the most common cause of inherited intellectual disability in males and the leading single-gene defect associated with autism. A full mutation (FM) is represented by more than 200 CGG repeats within the FMR1 gene, resulting in FXS. A FM is inherited from women carrying...
متن کاملThe Impact in Older Women of Ovarian FMR1 Genotypes and Sub-Genotypes on Ovarian Reserve
We recently associated ovarian FMR1genotypes and sub-genotypes with distinct ovarian aging patterns. How they impact older females is, however, unknown. We, therefore, investigated 217 consecutive first in vitro fertilization (IVF) cycles in women >40 assessing oocyte yields, stratified for better (anti-Müllerian hormone, AMH >1.05 ng/mL) or poorer (AMH ≤ 1.05 ng/mL) functional reserve (FOR)). ...
متن کاملEpigenetic Aberration of FMR1 Gene in Infertile Women with Diminished Ovarian Reserve
OBJECTIVES The diminished ovarian reserve (DOR) is a condition characterized by a reduction in the number and/or quality of oocytes. This primary infertility disorder is usually accompanied with an increase in the follicle-stimulating hormone (FSH) levels and regular menses. Although there are many factors contributing to the DOR situation, it is likely that many of idiopathic cases have geneti...
