|TTLL5 (14q24.3) / TSHR (14q31.1)|
|Note||Belongs to the rhodopsin-like G-protein coupled receptor superfamily (GPCR) and leucine-rich repeat containing GPCR family (LRG).|
|Structure of the TSHR gene and coding sequence (CDS). Boxes represent exons numbered 1 to 10 and proportional to length, red representing the coding sequence, grey representing untranslated regions (UTR); the horizontal line joining exons represents introns, shrunk to minimal length. Positions below the CDS are numbered relative to the transcription start.|
|Description||Spans 190,778 bp, contains 10 exons. Kakinuma and Nagayama (2002) identified 13 exons, but most findings relate to the 10-exon pattern.|
|Transcription|| Regulated by a TATA-less promoter containing binding sites for GABP, TTF1, CREB, ATF2, TR/RXR, SSBP and ICER.|
Major transcript (TSHR isoform 1 precursor, NM_000369.2) encoded by 10 exons, transcript length 4410 bp, 2295 bp ORF, ~100 bp 5' UTR and 1.6 kb 3' UTR; the coding region spans positions 157-2451 bp, with a signal peptide at 157-216 bp, mature peptide from 217 to 2448 bp, poly-A signal at 4371-4376. Encodes the canonical protein, 764 aa.
NCBI Entrez Gene describes two alternatively spliced variants, TSHR isoform 2 precursor (NM_001018036.1) and TSHR isoform 3 precursor (NM_001142626.1). Additional transcripts are possible; according to NCBI/Aceview, there are 10 alternatively spliced variants, based upon cDNAs deposited in GenBank derived from normal and neoplastic human tissues and cell lines. There are 3 probable alternative promoters, 6 non overlapping alternative last exons and 6 validated alternative polyadenylation sites. The mRNAs appear to differ by truncation of the 5' end, truncation of the 3' end, overlapping exons with different boundaries, alternative splicing or retention of 2 introns. There is no evidence for protein expression of splice variants.
|TSHR localization and structure. Left, thyroid follicle where the TSH-stimulated synthesis of thyroid hormone (T3 and T4) occurs following iodide uptake and organification into thyroglobulin (Tg). Right, TSHR protein structure, showing the A subunit composed of leucine-rich repeats (LRR) and the N-terminus, and the B subunit composed of 7 transmembrane domains (TMD), the intracellular and extracellular loops (ICL and ECL respectively) and the C-terminus.|
|Description|| G-protein coupled receptor (GPCR), 764 aa membrane glycoprotein. Predicted MW 84.5 kDa; apparent MW of glycosylated protein 95-120 kDa.|
Consists of two subunits:
(i) A or α subunit: encoded by exons 1-8 of TSHR gene; glycosylated extracellular ectodomain containing 9 leucine-rich repeats (LRR) and the N-terminus; binds TSH and other ligands (hCG and LH),
(ii) B or β subunit: encoded by exons 9-10 of TSHR gene; consists of 7 trans-membrane domains (TMD) connected by extracellular loops (important for basal and activated function) and intracellular loops (important for G protein coupling), and an intracellular C terminus.
A and B subunits are produced by posttranslational proteolytic cleavage of single-chain TSHR at the cell surface, with removal of a 50 aa peptide, and subsequent joining of A and B subunits by disulfide bridges. The B subunit is thought to be constitutionally active, and interaction with the A subunit ectodomain maintains the B subunit in an inactive state.
|Expression||Thyroid follicular epithelial cells; to a lesser degree in thymus, pituitary gland, lymphocytes, testis, retro-ocular fibroblasts, adipocytes, brain, heart and kidney.|
|Function|| Regulation of thyroid metabolism.|
TSHR is the receptor for thyrotropin (thyroid stimulating hormone or TSH), a member of the glycoprotein hormone family. TSH is released by the anterior pituitary gland and is the main regulator of thyroid gland growth and development. Binding of TSH to TSHR stimulates thyroid epithelial cell proliferation, and regulates the expression of differentiation markers such as thyroglobulin, thyroperoxidase and the sodium iodide symporter (NIS), necessary for the synthesis of thyroid hormones.
TSHR is coupled to heterotrimetric G proteins, regulatory proteins associated with the inner surface of the plasma membrane. Binding of TSH to TSHR causes a conformational change in TSHR, provoking the GTP-dependent dissociation of the Gα subunit from GβGγ dimers. Gα activates distinct signal transduction pathways to stimulate gene transcription and cell proliferation.
Two G protein-dependent pathways are activated by TSHR:
(i) Gαs activates adenylate cyclase to increase cAMP levels; cAMP activates protein kinase A (PKA) causing translocation of its catalytic subunit to the nucleus; PKA phosphorylates, among others, the transcription factor CREB thereby increasing its transcriptional activity.
(ii) Gαq activates phospholipase C to increase phosphoinositide turnover, releasing inositol triphosphate (IP3) and diacylglycerol (DAG); DAG activates protein kinase C, which promotes proliferation via the RAF/MEK/ERK pathway.
Complex cross-talk occurs between these pathways and other signaling pathways including the PI3/Akt, PKC/NFkB and JAK/STAT pathways (for reviews see García-Jiménez and Santisteban (2007) and Latif et al. (2009)).
TSHR is also activated by other members of the glycoprotein hormone family, including human chorionic gonadotropin (hCG), luteinizing hormone (LH) and thyrostimulin (a heterodimer composed of A2 and B5 glycoprotein hormone subunits).
|Homology||LHCGR (Luteinizing Hormone, Choriogonadotropin receptor) 51% amino acid identity; FSHR (Follicle Stimulating Hormone receptor) 48% amino acid identity.|
|Note|| Over 90 naturally occurring TSHR mutations have been identified, and are catalogued in the GRIS database and TSHR mutation database. Mutations are gain-of-function resulting in constitutional activation of the receptor independently of TSH, or loss-of-function resulting in loss of TSH sensitivity.|
Polymorphisms: Coding missense SNPs: Pro27Thr, Glu34Lys, Asp36His, Pro52Thr, Thr574Ser, Tyr601His, Val721Phe, Glu727Asp, Asn 744Lys.

Mutations are listed in terms of the amino acid residues altered and their respective location (α = A subunit, β = B subunit, TM = transmembrane domain, ICL = intracellular loop, ECL = extracellular loop, LRR = leucine-rich repeat, hinge = domain connecting leucine-rich repeats to first transmembrane domain).|
Note: * unknown functional status of mutations (Ohno et al., 1995).
|Germinal||Germinal TSHR mutations include missense mutations, nonsense mutations, insertion/deletions, and exon skipping due to alternative splicing. Germinal activating mutations are associated with hereditary or sporadic congenital hyperthyroidism, whereas germinal inactivating mutations are a cause of TSH resistance associated with congenital hypothyroidism and euthyroid hyperthyrotropinaemia.|
|Somatic||Somatic TSHR mutations include missense mutations and in-frame deletions. Activating mutations have been identified in hyperfunctioning thyroid adenoma and toxic multinodular goiter; few cases are associated with thyroid carcinoma. No somatic inactivating mutations have been described so far.|
5. Implicated in
|Disease|| Somatic activating TSHR mutations are a major cause of hyperfunctioning thyroid adenomas, benign neoplasms of thyroid follicular cells:|
- 10-80% of hyperfunctioning or 'hot' adenomas (i.e. ademomas with active radioiodide uptake and thyroid hormone synthesis) harbor somatic activating mutations (Parma et al., 1993; Russo et al., 1996; Führer et al., 2007). The highly variable frequency of mutations may reflect geographic differences.
- Activating mutations are largely located in exon 10 encoding the TSHR β-subunit, and are particularly frequent in the sixth transmembrane segment (TM6) important for coupling to G proteins.
- Mutations result in the constitutive activation of adenylate cyclase, stimulating thyrocyte proliferation and thyroid hormone synthesis. As a consequence, hyperfunctioning nodules provoke hyperthyroidism and thyrotoxicosis.
- Nonfunctioning or 'cold' adenomas (i.e. not able to accumulate radioiodide or synthesize thyroid hormones) do not harbor TSHR mutations.
|Entity||Toxic multinodular goiter (Plummer's disease)|
|Disease|| Somatic activating TSHR mutations are a major cause of Toxic Multinodular Goiter (TMNG), a hyperplastic thyroid enlargement with multiple bilateral nodules:|
- 70-80% of hyperfunctioning nodules of TMNG harbor somatic activating mutations, many of which are shared with hyperfunctioning thyroid adenoma suggesting a common pathogenic event (Tonacchera et al., 1998; Tonacchera et al., 2000).
- Different hyperfunctioning nodules within a goiter harbor may distinct TSHR activating mutations, confirming the polyclonal etiology of TMNG. In contrast, nonfunctioning nodules within the same goiter do not harbor mutations.
- TMNG is most common in iodine-deficient areas, and this may reflect the increased mutagenic load associated with chronic TSH stimulation and thyrocyte proliferation.
- A germline polymorphism of codon 727 of TSHR was reported to be associated with TMNG (Gabriel et al., 1999), however a subsequent study failed to substantiate this finding in a European population (Mulhberg et al., 2000).
|Prognosis|| TSHR mRNA in thyroid tumours: Reduced or absent TSHR mRNA in thyroid tumours is a negative prognostic marker, indicative of reduced effectiveness of radioiodine therapy. TSHR expression in thyroid carcinoma correlates with the state of differentiation of tumours, with loss of differentiation resulting in a loss of mRNA expression. Thus, well-differentiated carcinomas (papillary and follicular) show variable TSHR mRNA levels ranging from normal to markedly reduced, whereas undifferentiated anaplastic carcinoma shows absent TSHR mRNA (Brabant et al., 2001; Brönnegård et al., 1994; Shiels et al., 1999). TSHR regulates the thyroid expression of the iodide transporter NIS, and decreased TSHR expression impairs the iodine-concentrating capacity of thyroid tumours.|
Circulating TSHR mRNA: TSHR mRNA in peripheral blood has been suggested as a potential molecular marker of circulating thyroid carcinoma cells to aid in the differential diagnosis of malignant and benign thyroid disease preoperatively, and to detect residual, recurrent or metastatic thyroid cancer (Barzon et al., 2004; Chinnappa et al., 2004).
TSHR promoter methylation: TSHR promoter methylation may be a marker for malignancy in thyroid carcinoma (Xing et al., 2003).
|Oncogenesis|| TSHR mutations: Mutagenic screening of thyroid carcinomas reveals a low incidence of somatic TSHR mutations ranging from 0-22%, suggesting a limited role for TSHR mutations in the pathogenesis of thyroid carcinoma (Matsuo et al., 1993; Russo et al., 1995; Ohno et al., 1995; Spambalg et al., 1996; Esapa et al., 1997; Cetani et al., 1999).|
In most cases, somatic activating TSHR mutations occur in hyperfunctioning thyroid carcinomas:
- Met453Thr in papillary carcinoma with hyperfunctioning thyroid nodule (Mirescu et al., 2000).
- Ile486Phe in an autonomously functioning follicular carcinoma presenting a 'hot' nodule causing hyperthyroidism (Camacho et al., 2000).
- Leu512Arg in autonomously functioning papillary carcinoma with 'hot' nodule (Gozu et al., 2004).
- Thr620Ile in follicular carcinoma presenting as autonomous functioning thyroid nodule (Niepomniszcze et al., 2006).
- Ala623Ser in papillary carcinoma with high constitutive adenylate cyclase activity (Russo et al., 1995).
- Phe631Ile and Asp633Tyr in toxic metastasizing follicular thyroid carcinoma; no TSHR mutations in non-functioning lung metastases (Führer et al., 2003).
- Thr632Ile in thyroid hormone-producing follicular carcinoma (Spambalg et al., 1996).
- Asp633His in aggressive insular thyroid carcinoma (poorly-differentiated carcinoma) presenting as an autonomously functioning thyroid nodule and causing severe thyrotoxicosis; TSHR mutation also present in lymph node metastasis (Russo et al., 1997).
- Leu677Val in autonomously functioning Hürthle cell thyroid carcinoma causing thyrotoxicosis (Russo et al., 1999).
Rare cases of TSHR mutations in nonfunctioning thyroid carcinoma have also been reported:
- Thr632Ala in nonfunctioning follicular carcinoma (Spambalg et al., 1996).
- Ala623Ser activating mutation in papillary carcinoma with 'cold' nodule, in patient with past history of Graves' disease (De Cross et al., 2008).
The role of activating TSHR mutations in neoplastic transformation is unclear. Although TSHR activation stimulates thyrocyte proliferation, hyperfunctioning nodules (adenoma or toxic multinodular goiter) are rarely malignant, suggesting that constitutive activation of the cAMP cascade alone is insufficient for the malignant transformation of thyroid follicular cells.
Epigenetics: The TSHR gene promoter is frequently hypermethylated in thyroid carcinoma, with preferential methylation in undifferentiated carcinoma (Xing et al., 2003; Schagdarsurengin et al., 2006). In contrast, TSHR gene promoter is unmethylated in the normal thyroid and in benign tumours (thyroid adenoma). Hypermethylation results in TSHR gene silencing and reduced TSHR expression in some malignant thyroid tumours. In thyroid cancer cell lines, demethylating agents partially restore TSHR expression.
|Entity||Congenital nongoitrous hypothyroidism-1 (CHNG1)|
|Disease||Germline inactivation TSHR mutations are a cause of hereditary congenital nongoitrous hypothyroidism. Inactivating mutations result in variable degrees of TSH resistance, with clinical consequences ranging from euthyroid hyperthyrotropinemia to mild or severe hypothyroidism. CHNG1 is inherited in an autosomal recessive manner, manifesting in homozygotes or compound heterozygotes. However, subclinical hypothyroidism may also manifest in heterozygotes, suggesting autosomal dominant inheritance.|
|Entity||Hereditary nonautoimmune hyperthyroidism|
|Disease||Germline activating TSHR mutations are a cause of hereditary nonautoimmune congenital hyperthyroidism (autosomal dominant inheritance). Sporadic cases of nonautoimmune congenital hyperthyroidism result from de novo germinal mutations. Activating germline mutations result in constitutive activation of the cAMP pathway in thyrocytes. Mutations are predominantly in exon 10 encoding the transmembrane domains. One activating mutation (Arg183Lys) increases sensitivity towards hCG and manifests in women during pregnancy (familial gestational hyperthyroidism).|
