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.

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.
