Genes Regulating Spermatogenesis and Sperm Function Associated With Rare Disorders

Area of Science:

• Reproductive Biology
• Human Genetics
• Rare Diseases

Background:

• Spermatogenesis is crucial for producing fertilizing sperm, relying on Sertoli cells and specific gene regulation.
• Mutations in genes regulating spermatogenesis can lead to infertility and rare genetic disorders.
• Understanding the genetic links between spermatogenesis and rare diseases is essential for diagnosis and treatment.

Purpose of the Study:

• To identify genes that intersect spermatogenesis and rare genetic conditions.
• To elucidate the molecular mechanisms underlying these genetic intersections.
• To review genotype-phenotype associations and polymorphisms for identified genes.

Main Methods:

• Screening of public genetic databases (GARD, OMIM, ClinVar).
• Extensive literature search for gene-disease associations.
• Analysis of gene function in gametogenesis and fertilization using animal models.

Main Results:

• Identified 22 genes associated with 21 rare genetic conditions and defective spermatogenesis or sperm function.
• These genes regulate key aspects of spermatogenesis, including Sertoli cell function, meiosis checkpoints, spermiogenesis, and sperm motility.
• Several identified genes also play roles in female gametogenesis (folliculogenesis and oogenesis).

Conclusions:

• Established a link between genes regulating spermatogenesis and rare genetic disorders.
• Highlighted shared molecular mechanisms in gametogenesis and fertilization across species.
• Provides a foundation for further research into genetic infertility and rare disease etiology.
