THBD sequence variants potentially related to recurrent pregnancy loss

Area of Science:

• Genetics
• Reproductive Medicine
• Molecular Biology

Background:

• Recurrent pregnancy loss (RPL) affects many women, often with unknown causes (idiopathic RPL).
• The THBD gene, encoding the thrombin receptor on endothelial cells, is a potential candidate gene for RPL due to its biological roles.
• Identifying genetic factors in RPL is crucial for understanding its etiology and developing diagnostic markers.

Purpose of the Study:

• To investigate the role of the THBD gene in the etiology of recurrent pregnancy loss.
• To identify potential genetic markers for RPL within the THBD gene.
• To explore the association between THBD gene mutations and RPL.

Main Methods:

• Sequencing of the complete coding region of the THBD gene in 262 patients with RPL.
• Bioinformatics analysis to identify mutations and assess their significance.
• Screening of control populations to evaluate the mutation's prevalence.

Main Results:

• A specific mutation, THBD-p.Trp153Gly, was identified and suggested to be associated with RPL.
• Bioinformatics analysis and control screening provided strong evidence for this association.
• The identified mutation warrants further investigation for its role in RPL.

Conclusions:

• The THBD-p.Trp153Gly mutation is a potential contributor to recurrent pregnancy loss.
• This mutation may serve as a molecular marker for the diagnosis or prognosis of RPL.
• Further functional studies are required to validate these findings and their clinical utility.
