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.

Variant summary: AMHR2 c.160C>T (p.Arg54Cys) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 6.4e-05 in 250270 control chromosomes in the gnomAD database, including 1 homozygotes. This frequency is not significantly higher than estimated for a pathogenic variant in AMHR2 causing Persistent Mullerian duct syndrome, allowing no conclusion about variant significance. c.160C>T has been reported in the literature in the compound heterozygous state in at least 2 individuals affected with Persistent Mullerian duct syndrome (example, Imbeaud_1996, Tian_2022), including at least 1 individual carrying a pathogenic variant in trans. These data indicate that the variant may be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function. In vitro experiments showed this variant prevented binding of the ligand protein (encoded by AMH) and also eliminated the activation of a target gene by AMH, suggesting the activation pathway is disrupted by this variant (example, Belville_2009). The following publications have been ascertained in the context of this evaluation (PMID: 19457927, 8872466, 34810374). No submitters have cited clinical-significance assessments for this variant to ClinVar. Based on the evidence outlined above, the variant was classified as likely pathogenic. -
