'''MURCS association''' is a rare congenital disorder characterized by a combination of [[Müllerian duct]] aplasia, [[renal agenesis]], and [[cervicothoracic somite dysplasia]].

==Clinical Features==
== '''Cause''' ==
Patients with MURCS association typically present with:
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]].
* [[Müllerian agenesis]]: Absence or underdevelopment of the uterus and upper two-thirds of the vagina.
 
* [[Renal agenesis]] or ectopia: One or both kidneys may be absent or located in an abnormal position.
== '''Signs and symptoms''' ==
* [[Cervicothoracic somite dysplasia]]: Abnormalities in the vertebrae and ribs, which may lead to scoliosis or other spinal deformities.
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).
 
Additional symptoms might include fused spinal bones in the neck and upper back and hearing loss. 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.
 
For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed.  
80%-99% of people have these symptoms
* [[Aplasia]]/[[hypoplasia]] of the uterus(Absent/small uterus)
* [[Azoospermia]](Absent sperm in semen)
* Bicornuate uterus(Heart shaped uterus)
* Ectopic kidney(Abnormal kidney location)
* Low posterior hairline(Low hairline at back of neck)
* Renal agenesis(Absent kidney)
* Renal dysplasia
* Short neck(Decreased length of neck)
* Short stature(Decreased body height)
 
30%-79% of people have these symptoms
* Abnormality of the ribs(Rib abnormalities)
* Vertebral segmentation defect
 
5%-29% of people have these symptoms
* Hearing impairment(Deafness)

Diagnosis of MURCS association is based on clinical evaluation and imaging studies. [[Ultrasound]] and [[MRI]] are commonly used to assess the reproductive and renal systems, while [[X-ray]] or [[CT scan]] may be used to evaluate skeletal anomalies.

==Treatment==
Management of MURCS association is multidisciplinary, involving gynecologists, nephrologists, and orthopedic specialists. Treatment is symptomatic and supportive, focusing on:
Some reproductive abnormalities may benefit from surgery.  Individuals with MURCS association do not typically have hormone dysfunction, so hormone therapy may not be beneficial.
* Surgical correction of vaginal agenesis, if necessary, to allow for normal sexual function.
 
* Monitoring and management of renal function.

* Orthopedic interventions for skeletal abnormalities.

A rare congenital disorder affecting the reproductive and skeletal systems


MURCS association is a rare congenital disorder characterized by a combination of Müllerian duct aplasia, renal agenesis, and cervicothoracic somite dysplasia. It is considered a form of Mayer-Rokitansky-Küster-Hauser syndrome (MRKH), specifically type II, which involves additional anomalies beyond the reproductive system.

Etiology[edit]

The exact cause of MURCS association is not well understood, but it is believed to have a genetic component. The condition is often sporadic, but there have been cases suggesting an autosomal dominant pattern of inheritance, as depicted in the diagram.

Clinical Features[edit]

Patients with MURCS association typically present with:

  • Müllerian agenesis: Absence or underdevelopment of the uterus and upper two-thirds of the vagina.
  • Renal agenesis or ectopia: One or both kidneys may be absent or located in an abnormal position.
  • Cervicothoracic somite dysplasia: Abnormalities in the vertebrae and ribs, which may lead to scoliosis or other spinal deformities.

Diagnosis[edit]

Diagnosis of MURCS association is based on clinical evaluation and imaging studies. Ultrasound and MRI are commonly used to assess the reproductive and renal systems, while X-ray or CT scan may be used to evaluate skeletal anomalies.

Management[edit]

Management of MURCS association is multidisciplinary, involving gynecologists, nephrologists, and orthopedic specialists. Treatment is symptomatic and supportive, focusing on:

  • Surgical correction of vaginal agenesis, if necessary, to allow for normal sexual function.
  • Monitoring and management of renal function.
  • Orthopedic interventions for skeletal abnormalities.

Prognosis[edit]

The prognosis for individuals with MURCS association varies depending on the severity of the renal and skeletal anomalies. With appropriate management, many patients can lead normal lives.
