Genes affected

TACR3 (HGNC:11528): (tachykinin receptor 3) This gene belongs to a family of genes that function as receptors for tachykinins. Receptor affinities are specified by variations in the 5'-end of the sequence. The receptors belonging to this family are characterized by interactions with G proteins and 7 hydrophobic transmembrane regions. This gene encodes the receptor for the tachykinin neurokinin 3, also referred to as neurokinin B. [provided by RefSeq, Jul 2008]

Pathogenic, criteria provided, single submitter	clinical testing	GeneDx	Jun 06, 2022	Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; This variant is associated with the following publications: (PMID: 29419413, 29886503, 31200363, 23643382, 21300340, 25525159, 26207952, 28436984, 30665703, 23329188, 30450471, 20332248, 26792935, 26239645, 22035731, 31980526, 34426522, 33363893, 31589614, 34055685, 22031817) -
Pathogenic, criteria provided, single submitter	clinical testing	Genetic Services Laboratory, University of Chicago	Mar 29, 2019	DNA sequence analysis of the TACR3 gene demonstrated an apparently homozygous sequence change, c.824G>A, which results in the creation of a premature stop codon at amino acid position 275, p.Trp275*. This pathogenic sequence change is predicted to result in an abnormal transcript, which may be degraded, or may lead to the production of a truncated TACR3 protein with potentially abnormal function. This sequence change has been previously described in male patients with normosmic idiopathic hypogonadotropic hypogonadism in both homozygous and compound heterozygous state (Francou et al., 2011 and Gianetti et al., 2010). This sequence change has been described in the gnomAD database with a population frequency of 0.032% (rs144292455). -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	May 27, 2022	This sequence change creates a premature translational stop signal (p.Trp275*) in the TACR3 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TACR3 are known to be pathogenic (PMID: 20194706, 20332248, 22031817). This variant is present in population databases (rs144292455, gnomAD 0.06%). This premature translational stop signal has been observed in individual(s) with idiopathic hypogonadotropic hypogonadism (PMID: 33363893). ClinVar contains an entry for this variant (Variation ID: 66084). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. For these reasons, this variant has been classified as Pathogenic. -

Pathogenic, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 27, 2017	The TACR3 c.824G>A (p.Trp275Ter) variant is a stop-gained variant reported in four studies in which it is found in a total of 13 individuals with isolated gonadotropin-releasing hormone (GnRH) deficiency, including in three homozygotes, in three compound heterozygotes, in five heterozygotes, and in two individuals showing digenic inheritance (Gianetti et al. 2010; Quaynor et al. 2011; Xu et al. 2011; Francou et al. 2011). The variant was absent from over 800 controls, but is reported at a frequency of 0.00093 in the European American population of the Exome Sequencing Project. Based on the potential impact of stop-gained variants and the evidence from the literature, the p.Trp275Ter variant is classified as pathogenic for isolated GnRH deficiency. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -

Jun 22, 2024

The TACR3 c.824G>A variant is predicted to result in premature protein termination (p.Trp275*). This variant has been reported in the compound heterozygous and homozygous states, as well as in combination with variants in other genes, to be causative for hypogonadotropic hypogonadism (see for example - Gianetti et al. 2010. PubMed ID: 20332248; Xu et al. 2011. PubMed ID: 21300340). This variant is reported in 0.065% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Nonsense variants in TACR3 are expected to be pathogenic. This variant is interpreted as pathogenic. -
