Deficiency of the glycoprotein WNT4, associated with loss of function mutation(s) in the WNT4 gene. The condition in 46,XX individuals is characterized by mild hyperandrogenism, absence of underdevelopment of the uterus, and sometimes absence of underdevelopment of the vagina.
Features include always present findings: Aplasia of the fallopian tube, Unilateral renal agenesis, Aplasia of the uterus, and Aplasia of the vagina and others; and very common findings: Hirsutism. 10 total HPO annotations.

WNT4 function has not been fully characterized.
Mullerian aplasia and hyperandrogenism is associated with mutations in the WNT4 gene on chromosome 1.
Genetic testing for WNT4 is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 8 always present features, 1 very common feature.
Estimated prevalence: Unknown (Unknown prevalence).
No clinical trials have been registered for mullerian aplasia and hyperandrogenism.
2 publications have been identified in PubMed for mullerian aplasia and hyperandrogenism. Research spans Review / Meta-Analysis (50%) and Basic Science / Preclinical (50%).
