We describe successful controlled ovarian stimulation (COS) and the first known IVF pregnancy in a trisomy X carrier with associated hypogonadotropic hypogonadism (HH) linked to a chromosome 4 double mutation in the allele of the Gonadotropins Releasing Hormone receptor (GnRHr) gene.

In this article we summarize phenotypic characteristics of these patients and focus on specific functional alterations of the human GnRH-R. In-vitro studies using recombinant receptor constructs demonstrate that GnRH-R missense mutations result in impaired ligand binding and reduced signal transduction, causing gonadotrophin deficiency.

It should not have been surprising, in retrospect, to find that even a single amino acid mutation dramatically alters protein function or routing because increased plasma membrane expression is associated with deletion of a single amino acid in the human GnRHR (K191), and point mutations have been shown to block plasma membrane routing of many receptors, including most of those responsible for the hypogonadotropic hypogonadism phenotype.
