Genes affected
GNRHR (HGNC:4421): (gonadotropin releasing hormone receptor) This gene encodes the receptor for type 1 gonadotropin-releasing hormone. This receptor is a member of the seven-transmembrane, G-protein coupled receptor (GPCR) family. It is expressed on the surface of pituitary gonadotrope cells as well as lymphocytes, breast, ovary, and prostate. Following binding of gonadotropin-releasing hormone, the receptor associates with G-proteins that activate a phosphatidylinositol-calcium second messenger system. Activation of the receptor ultimately causes the release of gonadotropic luteinizing hormone (LH) and follicle stimulating hormone (FSH). Defects in this gene are a cause of hypogonadotropic hypogonadism (HH). Alternative splicing results in multiple transcript variants encoding different isoforms. More than 18 transcription initiation sites in the 5' region and multiple polyA signals in the 3' region have been identified for this gene. [provided by RefSeq, Jul 2008]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | May 24, 2023 | This variant is also known as two separate variants, c.30T>A (p.Asn10Lys) and c.31C>A (p.Gln11Lys). This variant, c.30_31delinsAA, is a complex sequence change that results in the deletion of 2 and insertion of 2 amino acid(s) in the GNRHR protein (p.Asn10_Gln11delinsLysLys). Information on the frequency of this variant in the gnomAD database is not available, as this variant may be reported differently in the database. This variant has been observed in individual(s) with Kallman syndrome or hypogonadotropic hypogonadism (PMID: 15240592, 31200363, 34198905; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 189195). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this variant affects GNRHR function (PMID: 15240592). For these reasons, this variant has been classified as Pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | Athena Diagnostics | Nov 11, 2022 | The frequency of this variant in the general population is consistent with pathogenicity (http://gnomad.broadinstitute.org). This variant segregates with disease in multiple families. Assessment of experimental evidence suggests this variant results in abnormal protein function. (PMID: 15240592) In multiple individuals, this variant has been seen with a single recessive pathogenic variant in the same gene, suggesting this variant may also be pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | May 04, 2022 | Published functional studies demonstrate a damaging effect on binding ability and inositol phosphate production (Meysing et al., 2004); In silico analysis supports that this variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 15240592, 29419413, 31200363, 23643382, 20696889, 22745237, 34198905, 31589614) - |
