The Clinical Study of Sex Chromosome Variants

Infertility is a disease that affects approximately 10% of couples world-wide. Causes of infertility are varied and include age-related decline in fecundity, other causes of ovulatory dysfunction, tubal and pelvic pathology, male causes, idiopathic, and multifactorial. The underlying genetic causes of infertility are incompletely understood. The purpose of this study ...

Treatment With HMG-COA Reductase Inhibitor of Growth and Bone Abnormalities in Children With Noonan Syndrome

Noonan syndrome (NS) is a relatively frequent autosomal dominant disorder characterised by facial dysmorphic features, heart defects, developmental delay, and short stature. This syndrome is mostly caused by gain-of-function mutations in the PTPN11 gene, encoding tyrosine phosphatase. The best-defined consequence of NS-causing mutants is an enhancement of Ras/MAPK activation that ...

Natural History of Noncirrhotic Portal Hypertension

Noncirrhotic Portal Hypertension (NCPH) includes a spectrum of chronic liver diseases characterized by increased pressure within the portal circulation in the absence of cirrhosis. The complications from NCPH are similar to that of cirrhosis induced portal hypertension which includes the development of gastrointestinal varices, portal hypertensive gastropathy, splenomegaly, sepsis and ...

UTHealth Turner Syndrome Research Registry

Turner syndrome (TS) is a common chromosomal disorder that affects approximately 1 in 2500 live female births. Complete or partial monosomy of one of the X chromosomes in a female is associated with various congenital heart defects (CHDs), which include aortic dilatation, coarctation of aorta and BAV. Congenital cardiovascular defects ...

Autologous Ovarian Tissue Transplantation

This investigation involves patient enrollment, thaw and surgical transplantation of previously collected cryopreserved ovarian cortical tissue, a series of follow-up assessments during the first 2 years after transplantation and an annual survey after year 2. Screening visit (standard fertility consultation): The subject will complete a medical and reproductive history to ...

Primary Ovarian Insufficiency: Phenotype and Optimal Treatment

Background: Primary ovarian insufficiency (POI) is an enigmatic condition that affects ~1/10,000 women by age 20. Sometimes referred to as "early menopause," POI is characterized by estrogen deficiency among other hormonal abnormalities that resemble the menopause. POI is a serious chronic condition with no cure. The clinical presentation or 'phenotype' ...

Injections of Autologous PRP in Women With Primary Ovarian Insufficiency

Premature ovarian failure is a loss of normal function before age 40, leading to infertility and hypoestrogenism. While POI is sometimes called premature menopause, it is not the same thing as menopause. Women with POI may still have occasional irregular periods and may even occasionally achieve a pregnancy. Symptoms of ...

Establishing the Diagnosis Standard and Analysis the Risk Factors of POI in Chinese Women

Premature ovarian insufficiency (POI) is a clinical syndrome defined by loss of ovarian activity before the age of 40 years. The POI guideline development group of ESHRE recommends the following diagnostic criteria: oligo/amenorrhea for at least 4 months and an elevated follicle stimulating hormone (FSH) level 25 mIU/mL on two ...

Phase N/A

Establishing of an Early Warming System of Premature Ovarian Insufficiency

Premature ovarian insufficiency (POI) is a clinical syndrome defined by loss of ovarian activity before the age of 40 years. The POI guideline development group of ESHRE recommends the following diagnostic criteria: oligo/ amenorrhea for at least 4 months and an elevated follicle stimulating hormone (FSH) level 25 mIU/mL on ...

Prospective Genetic Study in Patients With Ovarian Insufficiency

The cause of ovarian insufficiency and decline in ovarian reserve are not clear, but most researchers think the probable causes are mainly three aspects: chromosomal abnormalities, genetic factors and autoimmune diseasesBut the majority of patients with normal chromosome karyotype analysis. The screening of pathogenic genes in patients with normal karyotype ...
