Living with 46,XX ovarian dysgenesis-short stature syndrome

A rare genetic condition that can bring short height, periods that never start, and ovaries that did not fully develop.

Understanding 46,XX ovarian dysgenesis-short stature syndrome

46,XX ovarian dysgenesis-short stature syndrome is a rare genetic difference of sex development.

People have no periods (primary amenorrhea), short stature, and delayed bone age. Estradiol is low, and follicle-stimulating and luteinizing hormones are high. The uterus and ovaries may be absent or underdeveloped. Pubic and underarm hair come in late. Chromosomes are a typical 46,XX. GARD lists onset as teenager.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • No periods (primary amenorrhea)
  • Short stature
  • Delayed bone maturation
  • Low estradiol
  • High follicle-stimulating hormone
  • Low body weight

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists, hormone specialists, maternal-fetal medicine specialists and urinary and male reproductive system specialists.

  3. Consider genetic testing

    Changes in MCM9 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Resolve: The National Infertility Association may keep lists of experts for this condition.
