About this study

Official title: A Whole-genome Sequencing Base Study on Genetic Pathogenesis of Diminished Ovarian Reserve

The study aims to explore the genetic pathogenesis of diminished ovarian reserve via whole-genome sequencing technology in Chinese women.

Read the detailed description

Diminished ovarian reserve (DOR), a pathological condition of reduced quantity and quality of oocytes, has severe impairment on women fertility. Some women experience DOR may develop into premature ovarian insufficiency (POI), which defined as a cessation of function of ovaries in women younger than 40 years old. The pathogenesis of DOR is multiple and the etiology of most DOR remains obscure. Genetic factors, including chromosome abnormality, genetic variation, and non-coding RNA abnormal regulation are considered the major mechanisms of DOR. More than 12 gene mutations, detected by whole-exome sequencing (WES), have been implicated as potential causes of DOR. However, we have found that coding gene mutation detected by WES may only account for a small part of DOR. Whole-genome sequencing (WGS) has been developing into an important strategy for identifying exons, introns and mitochondrial DNA mutation. However, the application of WGS is still lacking in detecting pathogenic genes of DOR. Therefore, this study intends to explore the possible pathogenic genes by WGS in order to deeply and comprehensively understand the pathogenic mechanism of DOR.

Questions about this trial

What is this clinical trial studying?

An observational study of Diminished Ovarian Reserve, run by Nanfang Hospital, Southern Medical University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 15 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Shi-ling Chen, M.D, Ph.D (+86-020-62787604, chensl_92@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Genotype (time frame: 1/9/2020-31/12/2022). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jan 2021.
