MURCS association explained

MURCS association
Synonyms:Müllerian duct aplasia-renal dysplasia-cervical somite anomalies syndrome

MURCS association (a variant of Mayer-Rokitansky-Küster-Hauser syndrome) is a very rare developmental disorder[1] that primarily affects the reproductive and urinary systems involving MUllerian agenesis, Renal agenesis, Cervicothoracic Somite abnormalities.[2] It affects only females.

Genetics

Genetic heterogeneity is observed in MURCS association.[3]

Diagnosis

ExaminationTypical findings
Physical examination including a precautious pelvic exam by an experienced pediatric/adolescent gynecologist.Normal height, secondary sex characteristics, and hair growth.Normal external genitalia.Short blind-ending vagina (0–3 cm) with no cervix at the apex.No uterus detected by manual palpation.
Radiologic examination
US of internal genitalia (transvaginal/−perineal)aNo uterus or vaginal canal.Two functional ovaries.
Pelvic MRI scanConfirms the diagnosis.Determines the presence of rudimentary uterine buds or complete uterovaginal agenesis
Renal scan (by US or MRI)Renal abnormalities are found in approximately 30% of patients
Consider examinations for other associated malformations (e.g. EOS scan, otorhinopharyngeal assessment and echocardiographyVarious skeletal malformations (axis and limbs), hearing impairment and congenital heart defects (rare).
Biochemical analysis
Gonadotropins (FSH, LH)Normal levels following menstrual cycle
EstradiolNormal levels
Androgen statusNormal female levels
Chromosomal analysis (can be used to differentiate from 46,XY DSDs)46,XX
  1. Abbreviations: FSH follicle stimulating hormone, LH luteinizing hormone, MRI magnetic resonance imaging, US ultrasonography
  2. aTransabdominal US should be considered in younger patients.

Treatment

Management of vaginal agenesis: correction of vaginal agenesis in MRKH syndrome with creation of a functional neovagina has been a hallmark in the treatment. Various different surgical and non-surgical methods have been suggested for vaginal construction.[5]

Infertility and uterus transplantation (UTx): Uterus transplantation (UTx) has now emerged as the first true infertility treatment for women with MRKH syndrome and giving them full (gestational, genetic, legal) motherhood from start.[6]
