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.

Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 406 of the AMHR2 protein (p.Arg406Gln). This variant is present in population databases (rs137853104, gnomAD 0.003%). This missense change has been observed in individual(s) with clinical features of persistent Mullerian duct syndrome (PMID: 11549681). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. This variant is also known as G>A at nt. 6051. ClinVar contains an entry for this variant (Variation ID: 8629). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt AMHR2 protein function. Experimental studies have shown that this missense change affects AMHR2 function (PMID: 11549681, 19457927). -
