Disease Profile

Precocious puberty

Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

E22.8 E30.1


Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.


Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.


dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.


recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.


Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Other names (AKA)

Sexual precocity; Idiopathic sexual precocity; Familial precocious puberty


Precocious puberty is when a person's sexual and physical traits develop and mature earlier than normal. Normal puberty typically begins between ages 10 and 14 for girls, and ages 12 and 16 for boys. The start of puberty depends on various factors such as family history, nutrition and gender. The cause of precocious puberty is not always known. Some cases of precocious puberty are due to conditions that cause changes in the body's release of hormones. Treatment involves medications that can stop the release of sexual hormones.[1]


This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Several studies have looked at the long-term effects of treatment with hormone therapy on children with precocious puberty. Long-term hormone treatment has been found to be safe for the reproductive system and helpful in reaching target adult height levels.[2] Additionally, there is little evidence suggesting that long term hormone treatment is associated with psychological or behavioral problems. More studies are needed to determine this association.[3]
