Estrogen resistance syndrome

What it is

From: Orphanet

Estrogen resistance syndrome is a rare, genetic endocrine disease characterized by estrogen-receptor insensitivity to estrogens and the presence of elevated estrogen and gonadotropin serum levels. Clinical manifestations include absent breast development and primary amenorrhea in association with multicystic ovaries and/or hypoplastic uterus in female patients, normal or abnormal gonadal development in male patients and markedly delayed bone maturation, persistence of open epiphyses, reduced bone mineral density, and variable tall stature in both sexes. Glucose intolerance, hyperinsulinemia and lipid abnormalities may also be present.

Reported clinical features and what the terms mean

The following findings are associated with this condition in Orphanet. They are not a checklist for diagnosing yourself, and they do not all occur in every affected person. Some are examination, imaging or laboratory findings that cannot be recognised at home.

The frequency labels describe how often a finding was reported among people with the condition in the source. They do not give the chance that a person with that symptom has the condition. Definitions below reproduce HPO terminology; they explain the term, not the likely severity in an individual.

Abnormality of circulating hormone level · Very frequent (99-80%)

Concentration of a hormone in the blood circulation outside of normal limits.

Absence of secondary sex characteristics · Very frequent (99-80%)

No secondary sexual characteristics are present at puberty.

Breast hypoplasia · Very frequent (99-80%)

Underdevelopment of the breast.

Hypoplasia of the uterus · Very frequent (99-80%)

Underdevelopment of the uterus.

Increased circulating gonadotropin level · Very frequent (99-80%)

Overproduction of gonadotropins (FSH, LH) by the anterior pituitary gland.

Osteopenia · Very frequent (99-80%)

Osteopenia is a term to define bone density that is not normal but also not as low as osteoporosis. By definition from the World Health Organization osteopenia is defined by bone densitometry as a T score -1 to -2.5.

Osteoporosis · Very frequent (99-80%)

Osteoporosis is a systemic skeletal disease characterized by low bone density and microarchitectural deterioration of bone tissue with a consequent increase in bone fragility. According to the WHO criteria, osteoporosis is defined as a BMD that lies 2.5 standard deviations or more below the average value for young healthy adults (a T-score below -2.5 SD).

Overgrowth · Very frequent (99-80%)

Excessive postnatal growth which may comprise increased weight, increased length, and/or increased head circumference.

Tall stature · Very frequent (99-80%)

A height above that which is expected according to age and gender norms.

Absence of pubertal development · Very frequent (99-80%)

Delayed epiphyseal ossification · Very frequent (99-80%)

Enlarged polycystic ovaries · Very frequent (99-80%)

Marked delay in bone age · Very frequent (99-80%)

Primary amenorrhea · Very frequent (99-80%)

Other findings in the same source

Additional reported features include Acanthosis nigricans (Frequent (79-30%)); Acne (Frequent (79-30%)); Coronaryartery atherosclerosis (Frequent (79-30%)); Elevated tissue non-specific alkaline phosphatase (Frequent (79-30%)); Episodic abdominal pain (Frequent (79-30%)); Glucose intolerance (Frequent (79-30%)); Hyperinsulinemia (Frequent (79-30%)). This is a selected summary, not a complete description of the condition.

Inheritance in the source

Autosomal recessive

Frequency and the population described

From: Orphanet

Reported case(s): 2.0; Worldwide. This is a published case count, not prevalence. Point prevalence: <1 / 1 000 000; Worldwide; Class only.

Understanding the inheritance label

From: MedlinePlus Genetics

An autosomal recessive pattern usually involves disease-causing changes in both copies of a gene. Parents may each carry one altered copy without having the condition themselves. A genetic counsellor can explain carrier testing and reproductive implications using the actual laboratory findings, rather than the condition name alone.

Which doctor should you see?

The suggested department for discussing Estrogen resistance syndrome is Endocrinology, with a endocrinologist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.

Additional services that may be relevant, depending on the findings, include: Clinical Genetics.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• Which hormone or metabolic finding is important in this case?
• How should test timing and current medicines be taken into account?
• What follow-up would show whether the care plan is working?

Treatment discussions and follow-up

The material gathered for this draft does not provide a complete condition-specific treatment pathway for Estrogen resistance syndrome. That gap does not mean that treatment is unavailable. A clinician needs to establish the diagnosis and review current guidance before recommending medicines, procedures, rehabilitation or other support.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
