Abstract
Iodothyronine deiodinases represent a family of selenoproteins involved in peripheral and local homeostasis of thyroid hormone action. Deiodinases are expressed in multiple organs and thyroid hormone affects numerous biological systems, thus genetic variation in deiodinases may affect multiple clinical endpoints. Interest in clinical effects of genetic variation in deiodinases has clearly increased. We aimed to provide an overview for the role of deiodinase polymorphisms in human physiology and morbidity. In this systematic review, studies evaluating the relationship between deiodinase polymorphisms and clinical parameters in humans were eligible. No restrictions on publication date were imposed. The following databases were searched up to August 2013: Pubmed, EMBASE (OVID-version), Web of Science, COCHRANE Library, CINAHL (EbscoHOST-version), Academic Search Premier (EbscoHOST-version), and ScienceDirect. Deiodinase physiology at molecular and tissue level is described, and finally the role of these polymorphisms in pathophysiological conditions is reviewed. Deiodinase type 1 (D1) polymorphisms particularly show moderate-to-strong relationships with thyroid hormone parameters, IGF1 production, and risk for depression. D2 variants correlate with thyroid hormone levels, insulin resistance, bipolar mood disorder, psychological well-being, mental retardation, hypertension, and risk for osteoarthritis. D3 polymorphisms showed no relationship with inter-individual variation in serum thyroid hormone parameters. One D3 polymorphism was associated with risk for osteoarthritis. Genetic deiodinase profiles only explain a small proportion of inter-individual variations in serum thyroid hormone levels. Evidence suggests a role of genetic deiodinase variants in certain pathophysiological conditions. The value for determination of deiodinase polymorphism in clinical practice needs further investigation.

Abstract
CONTEXT Adequate thyroid hormone availability during fetal and early life is crucial for normal child growth and development. Fetal growth heavily depends on angiogenesis. Placental growth factor (PlGF) is a proangiogenic factor sharing high homology with vascular endothelial growth factor, whereas soluble FMS-like tyrosine kinase-1 (sFlt1) is a potent antagonist of vascular endothelial growth factor and PlGF signaling. Because the thyroid is a highly vascularized organ, we hypothesized that fetal angiogenic factors influence in utero thyrogenesis and impair newborn thyroid function. Therefore, we investigated the association between sFlt1 and PlGF on newborn thyroid function. DESIGN, SETTING, AND PARTICIPANTS sFlt1, PlGF, TSH, and free T4 (FT4) were determined in cord serum of 3525 newborns from a large prospective cohort study. Analyses were adjusted for relevant maternal and child covariates. RESULTS sFlt1 levels were positively associated with TSH (β 0.07 ± 0.02 mU/L; P < .001) and inversely with FT4 (β -0.58 ± 0.11; P < .001). PlGF showed a positive association with FT4 (β 0.19 ± 0.02; P < .001). Elevated levels of sFlt1 were associated with a 2.8-fold increased risk of hypothyroxinemia (P = .04). Decreased levels of PlGF were associated with a 6.7-fold increased risk of hypothyroxinemia (P < .001). Within the normal range, a dose-dependent effect of sFlt1 on thyroid dysfunction was observed: high-normal sFlt1 levels were associated with a 17.7-fold increased risk of hypothyroxinemia (P < .001) and a 2.7-fold increased risk of hyperthyrotropinemia (P = .01). CONCLUSION Fetal angiogenic factors sFlt1 and PlGF are associated with newborn thyroid function. Possible effects are most likely mediated through effects on in utero thyrogenesis. Abnormal as well as normal-range fetal sFlt1 and PlGF levels influence the risk of impaired newborn thyroid function, which has been associated with adverse neurodevelopmental effects. These data provide important novel insights into the physiology of thyrogenesis and into the etiology of newborn thyroid (dys)function.

Abstract
BACKGROUND Previously, we studied the genetic basis for variability in total thyroxine (TT4) as part of investigating induced Graves' hyperthyroidism in panels of genetically diverse recombinant inbred (RI) mice. Because Graves' disease occurs predominantly in women, we used female mice. A limitation of this approach is that thyrotropin (TSH) is undetectable by some assays in most female mice. METHOD Variation in levels of serum TSH, TT4, and free thyroxine (FT4) was measured in males from three related RI families (CXB, BXH, and AXBXA) followed by quantitative genetic analysis and mapping of these traits. RESULTS In general, TSH levels were higher in males than females. FT4 levels were also higher in males than in females, but TT4 sex differences were absent or inconsistent. Chromosomal linkage was only observed for TSH in BXH males and for FT4 in AXBXA males. Different chromosomes were linked to TT4 in males of the three RI sets. The most striking finding came from genetic linkages in males versus our previous data for females. TT4 was linked to the same chromosomal loci in CXB males and females. In contrast, TT4, FT4, and TSH were linked to different "sex-specific chromosomes" in AXBXA and BXH families. CONCLUSIONS In three RI mouse families, TSH and FT4 were significantly higher in males than females. Linkage analysis revealed chromosomal overlap for TT4 in males and females for one RI set but striking sex differences for TT4, FT4, and TSH linkage in two RI sets. Our findings provide a cautionary note: genetic linkage analysis of thyroid hormones traits in mice should be studied separately in males and females.

Abstract
Thyroid-stimulating hormone (TSH) is a sensitive indicator of thyroid function. High and low TSH levels reflect hypothyroidism and hyperthyroidism, respectively. Even within the normal range, small differences in TSH levels, on the order of 0.5-1.0 mU/l, are associated with significant differences in blood pressure, BMI, dyslipidemia, risk of atrial fibrillation and atherosclerosis. Most of the variance in TSH levels is thought to be genetically influenced. We conducted a genome-wide association study of TSH levels in 1346 Chinese Han individuals. In the replication study, we genotyped four candidate SNPs with the top association signals in an independent isolated Chinese She cohort (n = 3235). We identified a novel serum TSH susceptibility locus within XKR4 at 8q12.1 (rs2622590, Pcombined = 2.21 × 10(-10)), and we confirmed two previously reported TSH susceptibility loci near FOXE1 at 9q22.33 and near CAPZB at 1p36.13, respectively. The rs2622590_T allele at XKR4 and the rs925489_C allele near FOXE1 were correlated with low TSH levels and were found to be nominally associated to patients with papillary thyroid carcinoma (PTC) (OR = 1.41, P= 0.014 for rs2622590_T, and OR = 1.61, P= 0.030 for rs925489_C). The rs2622590 and rs925489 genotypes were also correlated with the expression levels of FOXE1 and XKR4, respectively, in PTC tissues (P = 2.41 × 10(-4) and P= 0.02). Our findings suggest that the SNPs in XKR4 and near FOXE1 are involved in the regulation of TSH levels.

Abstract
OBJECTIVE Data on reference intervals of thyroid functions in Southeast Asia are limited. The aim of this study was to provide reference ranges of thyroid functions and thyroid autoantibodies in Thais. DESIGN AND METHODS Serum samples from 2545 apparently healthy non-pregnant subjects, aged ≥14 years, from the fourth Thai National Health Examination Survey were measured for TSH, FT4, antithyroperoxidase (TPO Ab), antithyroglobulin (Tg Ab) and antithyrotrophin receptor antibodies (TRAb). A reference population was selected from the disease-free population by excluding those who had thyroid autoantibodies and TSH > 20 mIU/l. RESULTS For the total population, median TSH and FT4 levels were 1·94 mIU/l and 1·35 ng/dl, respectively. TSH was higher and FT4 was lower in females than in males. Based on National Academy of Clinical Biochemistry criteria, the reference intervals (2·5th-97·5th percentile) were: TSH, 0·34-5·11 mIU/l; FT4, 0·98-1·79 ng/dl; TPO Ab, 5-84·88 IU/ml; Tg Ab, 10-118·2 IU/ml; and TRAb, 0·3-1·24 IU/l. With the new reference ranges, hypothyroidism was found in 4·16% of the total population (0·78% overt and 3·38% subclinical hypothyroidism) and hyperthyroidism was found in 3·18% (0·94% overt and 2·24% subclinical hyperthyroidism). Positive TPO Ab, Tg Ab and TRAb were found in 8·96%, 12·26% and 5·93%, respectively. The upper normal limit of TSH tended to increase with age, particularly for those aged 80 years and older. CONCLUSIONS The reference interval for TSH needs to be derived from each specific population. Slightly elevated TSH concentrations in the elderly could be considered acceptable, with no need for thyroxine treatment.

Abstract
Genetic factors are thought to be an important determinant of thyroid function and autoimmunity. However, there are limited data on genetic variants in Asians. In this study, we performed a genome-wide association study on plasma thyroid-stimulating hormone (TSH) and free thyroxine (fT4) concentration and anti-thyroid peroxidase (anti-TPO) antibody positivity in 4238 Korean subjects. In the Stage 1 genome scan, 3396 participants from the Ansung cohort were investigated using 1.42 million genotyped or imputed markers. In the Stage 2 follow-up, 10 markers were genotyped in 842 participants from the Korean Longitudinal Study on Health and Aging cohort. An intronic variant in VAV3, rs12126655, which has been reported in Europeans, was significantly associated with plasma TSH concentration in the joint Stages 1 and 2 analyses (P = 2.2 × 10(-8)). We observed that a novel variant, rs2071403, located 75 bp proximal to the translational start site of TPO was significantly associated with plasma anti-TPO antibody positivity in the joint Stages 1 and 2 analyses (P = 1.3 × 10(-10)). This variant had a marginal sex-specific effect, and its association was more significant in females. Subjects possessing the rs2071403A allele, associated with an absence of the anti-TPO antibody, had decreased TPO mRNA expression in their thyroid tissue. Another intronic variant of HLA-DPB2, rs733208, had a suggestive association with anti-TPO antibody positivity (P = 4.2 × 10(-7)). In conclusion, we have identified genetic variants that are strongly associated with TSH level and anti-TPO antibody positivity in Koreans. Further replications and meta-analysis are required to confirm these findings.

Abstract
BACKGROUND NKX2-1 encodes a transcription factor with large impact on the development of brain, lung and thyroid. Germline mutations of NKX2-1 can lead to dysfunction and malformations of these organs. Starting from the largest coherent collection of patients with a suspected phenotype to date, we systematically evaluated frequency, quality and spectrum of phenotypic consequences of NKX2-1 mutations. METHODS After identifying mutations by Sanger sequencing and array CGH, we comprehensively reanalysed the phenotype of affected patients and their relatives. We employed electrophoretic mobility shift assay (EMSA) to detect alterations of NKX2-1 DNA binding. Gene expression was monitored by means of in situ hybridisation and compared with the expression level of MBIP, a candidate gene presumably involved in the disorders and closely located in close genomic proximity to NKX2-1. RESULTS Within 101 index patients, we detected 17 point mutations and 10 deletions. Neurological symptoms were the most consistent finding (100%), followed by lung affection (78%) and thyroidal dysfunction (75%). Novel symptoms associated with NKX2-1 mutations comprise abnormal height, bouts of fever and cardiac septum defects. In contrast to previous reports, our data suggest that missense mutations in the homeodomain of NKX2-1 not necessarily modify its DNA binding capacity and that this specific type of mutations may be associated with mild pulmonary phenotypes such as asthma. Two deletions did not include NKX2-1, but MBIP, whose expression spatially and temporarily coincides with NKX2-1 in early murine development. CONCLUSIONS The high incidence of NKX2-1 mutations strongly recommends the routine screen for mutations in patients with corresponding symptoms. However, this analysis should not be confined to the exonic sequence alone, but should take advantage of affordable NGS technology to expand the target to adjacent regulatory sequences and the NKX2-1 interactome in order to maximise the yield of this diagnostic effort.

Abstract
Congenital hypothyroidism (CH) is the most frequent endocrine disorder in neonates. While several genetic mutations have been identified that result in developmental defects of the thyroid gland or thyroid hormone synthesis, genetic factors have yet to be identified in many CH patients along with the mechanisms underlying their pathophysiology. Mutations in the gene encoding the Krüppel-like transcription factor, GLI-similar 3 (GLIS3) have been associated with the development of a syndrome characterized by congenital hypothyroidism and neonatal diabetes and similar phenotypes were observed in mouse knockout models of Glis3. Patients with GLIS3-mediated CH exhibit diminished serum levels of thyroxine (T4) and triiodothyronine (T3) and elevated thyroid stimulating hormone (TSH) and thyroglobulin (TG). However, the inconsistent presentation of clinical features associated with this CH has made it difficult to ascertain a causative mechanism. Future elucidation of the biological functions of GLIS3 in the thyroid will be crucial to the discovery of new therapeutic opportunities for the treatment of CH.

Abstract
MicroRNAs (miRNAs) are important regulators of gene expression and translation. The genetic variants altering miRNA targets have been associated with many diseases. Here we systematically mapped the human genetic polymorphisms that may affect miRNA-mRNA interactions in the autoimmune thyroid disease (AITD) pathway. We also mapped the polymorphic miRNA target sites in the genes that have been linked to AITDs or other thyroid-related diseases/phenotypes in genome-wide association studies (GWAS). These genetic polymorphisms may potentially contribute to the pathogenesis of AITDs and other thyroid diseases. The polymorphic miRNA-mRNA interactions we mapped in the AITD pathway and the GWAS-informed thyroid disease loci may provide insights into the possible miRNA-mediated molecular mechanisms through which genetic variants assert their influences on thyroid diseases and phenotypes.

Abstract
Animal models and epidemiological studies suggest that mild maternal thyroid hormone deficiency in early gestation has adverse consequences on the cognitive abilities of the children. However, methodological problems, lack of a consistent definition for mild thyroid hormone deficiency, and short follow-up of the children reduce the confidence in the conclusion of existing studies. In this review, we summarize the main findings of a series of studies performed in Generation R, a population-based birth cohort in Rotterdam, the Netherlands. In this iodine sufficient region, we aimed to investigate the relation between mild maternal thyroid hormone deficiency in early gestation and children's verbal and nonverbal cognitive function and executive function. We discuss the main findings of these studies, present recommendations for clinicians and formulate suggestions for future research.

Abstract
Autoimmune thyroid diseases (AITD) are common, affecting 2-5% of the general population. Individuals with positive thyroid peroxidase antibodies (TPOAbs) have an increased risk of autoimmune hypothyroidism (Hashimoto's thyroiditis), as well as autoimmune hyperthyroidism (Graves' disease). As the possible causative genes of TPOAbs and AITD remain largely unknown, we performed GWAS meta-analyses in 18,297 individuals for TPOAb-positivity (1769 TPOAb-positives and 16,528 TPOAb-negatives) and in 12,353 individuals for TPOAb serum levels, with replication in 8,990 individuals. Significant associations (P<5×10(-8)) were detected at TPO-rs11675434, ATXN2-rs653178, and BACH2-rs10944479 for TPOAb-positivity, and at TPO-rs11675434, MAGI3-rs1230666, and KALRN-rs2010099 for TPOAb levels. Individual and combined effects (genetic risk scores) of these variants on (subclinical) hypo- and hyperthyroidism, goiter and thyroid cancer were studied. Individuals with a high genetic risk score had, besides an increased risk of TPOAb-positivity (OR: 2.18, 95% CI 1.68-2.81, P = 8.1×10(-8)), a higher risk of increased thyroid-stimulating hormone levels (OR: 1.51, 95% CI 1.26-1.82, P = 2.9×10(-6)), as well as a decreased risk of goiter (OR: 0.77, 95% CI 0.66-0.89, P = 6.5×10(-4)). The MAGI3 and BACH2 variants were associated with an increased risk of hyperthyroidism, which was replicated in an independent cohort of patients with Graves' disease (OR: 1.37, 95% CI 1.22-1.54, P = 1.2×10(-7) and OR: 1.25, 95% CI 1.12-1.39, P = 6.2×10(-5)). The MAGI3 variant was also associated with an increased risk of hypothyroidism (OR: 1.57, 95% CI 1.18-2.10, P = 1.9×10(-3)). This first GWAS meta-analysis for TPOAbs identified five newly associated loci, three of which were also associated with clinical thyroid disease. With these markers we identified a large subgroup in the general population with a substantially increased risk of TPOAbs. The results provide insight into why individuals with thyroid autoimmunity do or do not eventually develop thyroid disease, and these markers may therefore predict which TPOAb-positives are particularly at risk of developing clinical thyroid dysfunction.

Abstract
OBJECTIVE High serum thyrotropin (TSH) levels predict cardiovascular disease (CVD). Recently several single nucleotide polymorphisms (SNPs) associated with TSH levels have been identified, one of them being the rs4704397 SNP in the phosphodiesterase 8B (PDE8B) gene. If the relation between thyroid function and CVD is causal, one could also expect rs4704397 genotypes to predict CVD and possibly health in general. METHODS DNA was prepared and genotyping performed for rs4704397 in subjects who participated in the fourth survey of the Tromsø Study in 1994-1995 and who were registered with the endpoints myocardial infarction (MI), type 2 diabetes (T2DM), cancer, or death, as well as a randomly selected control group. Similarly, genotyping was performed in subjects who had participated in clinical trials where serum TSH, free T4 (fT4), and free T3 (fT3) were measured. RESULTS From the Tromsø Study, 8938 subjects without thyroid disease or thyroid medication were successfully genotyped for rs4704397. Among these, 2098 were registered with MI, 1025 with T2DM, 2748 with cancer, and 3592 had died. The minor homozygote genotype (A:A) had a median serum TSH level that was 0.29 mIU/L higher than in the major homozygote genotype (G:G). The A:A genotype had a significantly increased risk of MI as compared to the G:G genotype (1.14 [1.00-1.29], hazard ratio [confidence interval], Cox regression with adjustment for age, sex, and body mass index). No significant associations were seen with the other endpoints or CVD risk factors. Furthermore, subjects with the G:G genotype were significantly taller than subjects with the A:A genotype (mean difference 1.5 cm). In 584 subjects with serum TSH, fT4, and fT3 measurements, the subjects with the A:A genotype had significantly higher serum TSH and nonsignificantly lower serum fT3 (mean difference 0.15 pmol/L) levels than subjects with the G:G genotype. CONCLUSION rs4704397 is associated with thyroid function, risk of MI, and body height. However, confirmation in other cohorts is needed before firm conclusions can be drawn.

Abstract
The thyroid pathway represents a complex interaction of different glands for thyroid hormone synthesis. Thyrotropin releasing hormone is synthesized in the hypothalamus and regulates thyrotropin stimulating hormone gene expression in the pituitary gland. In order to understand the complexity of the thyroid pathways, and using experimental data retrieved from the biomedical literature (e.g., NCBI, HuGE Navigator, Protein Data Bank, and KEGG), we constructed a metabolic map of the thyroid hormone pathway at a molecular level and analyzed it topologically. A total of five hub nodes were predicted in regards to the transcription thyroid receptor (TR), cAMP response element-binding protein (CREB), signal transducer and activator of transcription 3 (STAT 3), nuclear factor kappa-light-chain-enhancer of activated B cells (NFkB), and activator protein 1 (AP-1) as being potentially important in study of thyroid disorders and as novel putative therapeutic drug targets. Notably, the thyroid receptor is a highly connected hub node and currently used as a therapeutic target in hypothyroidism. Our analysis represents the first comprehensive description of the thyroid pathway, which pertains to understanding the function of the protein and gene interaction networks. The findings from this study are therefore informative for pathophysiology and rational therapeutics of thyroid disorders.

Abstract
Exposure to maternal hypothyroxinemia during pregnancy, which is characterized by low free T4 but normal thyroid-stimulating hormone (TSH) levels, can negatively affect the foetus. This review provides an overview of present findings concerning the association between maternal hypothyroxinemia during pregnancy and childhood cognitive functioning. Possible causes of maternal hypothyroxinemia and potential mechanisms underlying this association are also discussed. Clinical and epidemiological studies suggest that maternal hypothyroxinemia in the first half of pregnancy but not later in pregnancy impairs cognitive development in infancy and childhood. Animal models confirm that the first half of pregnancy may constitute a sensitive period in which maternal hypothyroxinemia alters neurogenesis and causes neuronal migration errors in the developing foetal brain. However, observational studies in humans cannot demonstrate causality of the association between hypothyroxinemia and neurodevelopment. In the only completed randomized trial of antenatal thyroid screening and subsequent levothyroxine treatment of mild maternal subclinical thyroid dysfunction, including hypothyroxinemia, the interventions did not affect offspring intelligence quotient (IQ). More randomized trials are needed investigating whether screening for hypothyroxinemia and its treatment earlier in the first trimester of pregnancy can improve child cognitive functioning or prevent neurodevelopmental changes. Long-term observational studies should identify molecular, neuroanatomical and neurophysiological factors involved in the association between maternal hypothyroxinemia and offspring cognitive functioning. Information on such mechanisms can be used for the development of innovative prevention and intervention studies that address maternal hypothyroxinemia and its potential consequences.
