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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

PM1

In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 uncertain in NM_000406.3

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 24 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 0.30095 (below the threshold of 3.09). Trascript score misZ: 0.14426 (below the threshold of 3.09). GenCC associations: The gene is linked to hypogonadotropic hypogonadism 7 with or without anosmia, hypogonadotropic hypogonadism.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.965

PP5

Variant 4-67740616-T-C is Pathogenic according to our data. Variant chr4-67740616-T-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 16025.Status of the report is criteria_provided_single_submitter, 1 stars.
