This study examined six female patients with 45X/46XY karyotype, finding two with pure gonadal dysgenesis and four with mixed gonadal dysgenesis. Early gonad revision and extirpation are recommended due to potential malignancy risks.

Area of Science:

  • Reproductive Endocrinology
  • Human Genetics
  • Pediatric Endocrinology

Background:

  • Understanding gonadal dysgenesis in individuals with 45X/46XY karyotype is crucial for clinical management.
  • The 45X/46XY karyotype presents a spectrum of gonadal abnormalities, impacting sexual development.
  • The hypothalamus-pituitary-gonadal axis function in these patients requires detailed investigation.

Observation:

  • Six patients with a female phenotype and 45X/46XY karyotype were analyzed.
  • Two patients presented with pure gonadal dysgenesis, while four exhibited mixed gonadal dysgenesis.
  • The integrity of the hypothalamus-pituitary-gonadal axis was noted in all observed cases.

Findings:

  • Patients with 45X/46XY karyotype demonstrate varying degrees of gonadal dysgenesis.

  • Pure and mixed gonadal dysgenesis present distinct clinical and genetic profiles.
  • The hypothalamus-pituitary-gonadal axis remains functional despite gonadal abnormalities.

    • Implications:

    • Surgical intervention, including gonad revision and extirpation, is recommended for patients with dysgenetic gonads.
    • Proactive management is essential to mitigate the risk of malignant transformation in dysgenetic gonads.
    • Further research into the long-term outcomes and optimal management strategies for 45X/46XY gonadal dysgenesis is warranted.
