Familial 46,XX gonadal dysgenesis

Area of Science:

• Reproductive Endocrinology
• Pediatric Endocrinology
• Genetics

Background:

• Secondary amenorrhea is a common gynecological issue in adolescents.
• Primary ovarian failure can present with amenorrhea, necessitating a thorough etiological investigation.
• Normal karyotypes in patients with gonadal dysgenesis suggest non-chromosomal causes.

Observation:

• Two sisters aged 16 and 17 presented with secondary amenorrhea.
• Both sisters had a history of mumps infection contracted simultaneously 10 years prior.
• Clinical evaluation revealed primary ovarian failure and gonadal dysgenesis despite normal karyotypes.

Findings:

• A significant correlation was observed between childhood mumps infection and the subsequent development of secondary amenorrhea.
• The findings suggest that environmental factors, such as viral infections during childhood, can contribute to gonadal dysgenesis.
• The simultaneous occurrence in siblings points towards shared environmental exposures or genetic predispositions.

Implications:

• Childhood mumps should be considered a potential risk factor for developing gonadal dysgenesis and secondary amenorrhea.
• This case underscores the importance of including gonadal dysgenesis in the differential diagnosis of secondary amenorrhea, particularly with a history of childhood infections.
• Further research into the long-term effects of childhood infections on ovarian function is warranted.
