Genes affected
AMHR2 (HGNC:465): (anti-Mullerian hormone receptor type 2) This gene encodes the receptor for the anti-Mullerian hormone (AMH) which, in addition to testosterone, results in male sex differentiation. AMH and testosterone are produced in the testes by different cells and have different effects. Testosterone promotes the development of male genitalia while the binding of AMH to the encoded receptor prevents the development of the mullerian ducts into uterus and Fallopian tubes. Mutations in this gene are associated with persistent Mullerian duct syndrome type II. Alternatively spliced transcript variants encoding different isoforms have been identified.

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMar 20, 2018This sequence change creates a premature translational stop signal (p.Asp44Argfs*40) in the AMHR2 gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with AMHR2-related disease. Loss-of-function variants in AMHR2 are known to be pathogenic (PMID: 8872466). For these reasons, this variant has been classified as Pathogenic. -
