Disease Profile

MURCS association

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.

Age of onset





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.

MURCS association stands for (MU)llerian, (R)enal, (C)ervicothoracic (S)omite abnormalities and is a developmental disorder that primarily affects the reproductive and urinary systems. Most individuals with MURCS association are female, although males can also have this condition. Females with MURCS association can have an absent or abnormally shaped uterus. In rare cases, the vagina is also affected. Both males and females with MURCS association can have absent or abnormally formed reproductive tubes (usually the fallopian tubes in females and the vas deferens in males), kidney abnormalities, and short stature (adult height of less than 5 feet). [1][2] Additional symptoms might include fused spinal bones in the neck and upper back and hearing loss.[2] These symptoms may vary from person to person. MURCS association is present at birth but may not be noticed until after puberty, especially when an affected female does not receive her first period. This condition does not alter a person’s life expectancy.[1][2]


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.

The cause of MURCS association is not known. Most affected individuals have no history of the condition in their family. Symptoms of the condition develop during pregnancy but have not been linked to any known teratogens. [1][2]


Some reproductive abnormalities may benefit from surgery. [3] Individuals with MURCS association do not typically have hormone dysfunction, so hormone therapy may not be beneficial. [4]
