Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 4P and 2B. PM2PM5BP4_Moderate

The NM_020547.3(AMHR2):c.161G>A(p.Arg54His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000198 in 1,613,600 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R54C) has been classified as Likely pathogenic.

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.

The c.161G>A (p.R54H) alteration is located in exon 2 (coding exon 2) of the AMHR2 gene. This alteration results from a G to A substitution at nucleotide position 161, causing the arginine (R) at amino acid position 54 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
