Investigation of a unique male and female sibship with Kallmann's syndrome and 46,XX gonadal dysgenesis with short stature. (1/110)

A sibship is described where the brother and a sister both have Kallmann's syndrome (anosmia and deficiency of gonadotrophin releasing hormone) and the woman also has streak ovaries. Although there are several conditions that may occur with Kallmann's syndrome, there are no known reports of ovarian dysgenesis being associated with this disorder. Cytogenetic analysis showed no rearrangement or major deletions of the chromosomes. Linkage analysis using informative microsatellite markers predicts that a gene other than KAL1 (at Xp22.3) is implicated in the Kallmann's syndrome manifesting concurrently with ovarian dysgenesis found in this family.  (+info)

Developmental and genetic disorders in spermatogenesis. (2/110)

The most common cause of male infertility is idiopathic. Fresh insights based on genetic and molecular analysis of the human genome permit classification of formerly unexplained disorders in spermatogenesis. In this article, we review new procedures that expand diagnostic and therapeutic approaches to male infertility. Recombinant DNA technology makes it possible to detect specific chromosomal and/or genetic defects among infertile patients. The identification of genes linked to disorders in spermatogenesis and male sexual differentiation has increased exponentially in the past decade. Genetic defects leading to male factor infertility can now be explained at the molecular level, even though the germ cell profile of infertile patients is too variable to permit classification of the clinical phenotype. Increasing knowledge of genes that direct spermatogenesis provides important new information about the molecular and cellular events involved in human spermatogenesis. Molecular analysis of chromosomes and/or genes of infertile patients offers unique opportunities to uncover the aetiology of genetic disorders in spermatogenesis. Increasing numbers of cases, previously classified as idiopathic, can now be diagnosed to facilitate the treatment of infertile men. Advanced knowledge also poses ethical dilemmas, since children conceived with assisted reproductive technologies such as intracytoplasmic sperm injection (ICSI) are at risk for congenital abnormalities, unbalanced complements of chromosomes and male infertility.  (+info)

Anosmin-1 is a regionally restricted component of basement membranes and interstitial matrices during organogenesis: implications for the developmental anomalies of X chromosome-linked Kallmann syndrome. (3/110)

Kallmann syndrome is a developmental disease characterized by gonadotropin-releasing hormone (GnRH) deficiency and olfactory bulb hypoplasia. The gene underlying the X chromosome-linked form, KAL-1, has been identified for several years, yet the pathogenesis of the disease is not understood. By immunohistofluorescence and immunoelectron microscopy, we establish that the KAL-1 encoded protein, anosmin-1, is a transient and regionally restricted component of extracellular matrices during organogenesis in man. Anosmin-1 was detected in the basement membranes and/or interstitial matrices of various structures including bronchial tubes, mesonephric tubules and duct, branches of the ureteric bud, muscular walls of the digestive tract and larger blood vessels, precartilaginous models of skeletal pieces, muscle tendons, head mesenchymes, inner ear, and forebrain subregions. Our results suggest that this protein acts as a local, rather than a long-range, cue during organogenesis. In the olfactory system, anosmin-1 was detected from week 5 onward. The protein was restricted to the olfactory bulb presumptive region and later, to the primitive olfactory bulbs. We therefore suggest that the genetic defect underlying X-linked Kallmann syndrome disrupts the terminal navigation of the early olfactory axons or directly affects the initial steps of olfactory bulb differentiation. The mechanism of the GnRH deficiency is also discussed, relying on the evidence that anosmin-1 is present in the medial walls of the primitive cerebral hemispheres, along the rostro-caudal migratory pathway of the GnRH-synthesizing neurons, at 6 weeks. Finally, the present results strongly suggest that the renal aplasia observed in about one third of the affected individuals results from primary failure of the collecting duct system.  (+info)

Episodic leptin release is independent of luteinizing hormone secretion. (4/110)

Several studies suggest that leptin modulates hypothalamic-pituitary-gonadal axis functions. Leptin may stimulate release of gonadotrophin releasing hormone (GnRH) from the hypothalamus and of gonadotrophins from the pituitary. A synchronicity of luteinizing hormone (LH) and leptin pulses has been described in healthy women and in patients with polycystic ovarian syndrome, suggesting that leptin may modulate the episodic secretion of LH. However, it has not been established whether LH regulates the episodic secretion of leptin. To further examine LH-leptin interactions, we studied the episodic fluctuations of circulating LH and leptin in two patients with Kallmann's syndrome (KS) before and on day 7 of pulsatile GnRH administration, and compared these with those observed in the early follicular phase of 10 regularly menstruating women divided into two control groups according to the body mass index of each patient. To assess episodic hormone secretion, blood samples were collected at 10 min intervals for 6 h, before and on day 7 of GnRH administration in KS patients, and during days 3-7 of the follicular phase in normally cycling women. LH and leptin concentrations were measured in all samples. For pulse analysis, the cluster algorithm was used. Before treatment, an apulsatile pattern with no endogenous LH pulsations was observed in both KS patients. However, leptin pulses were assessed in both women. During GnRH administration, pulsatile LH activity was achieved in both patients with pulse characteristics similar to those of the respective control group. Serum leptin concentrations and leptin pulsatile patterns were not modified. These results suggest that circulating leptin is probably not modulated by pulsatile GnRH-LH secretion.  (+info)

Characterization of the two zebrafish orthologues of the KAL-1 gene underlying X chromosome-linked Kallmann syndrome. (5/110)

The gene underlying X chromosome-linked Kallmann syndrome, KAL-1, has been identified for several years, yet its role in development is still poorly understood. In order to take advantage of the zebrafish as a model in developmental genetics, we isolated the two KAL-1 orthologues, kal1.1 and kal1.2, in this species. Comparison of deduced protein sequences with the human one shows 75.5 and 66.5% overall homology, respectively. The most conserved domains are the whey acidic protein-like domain and the first of four fibronectin-like type III repeats. However, kal1.2 putative protein lacks the basic C-terminal domain (20 residues) found in kal1.1 and KAL-1. The expressions of kal1.1 and kal1.2 were studied in the embryo between 6 and 96 hours post fertilization using whole-mount in situ hybridization. Although a few structures express both genes, kal1.1 and kal1.2 expression patterns are largely non-overlapping. Taken together, these patterns match fairly well those previously reported for human KAL-1 and chicken kal1. As regards the olfactory system, kal1.1 is expressed, from 37 h.p.f. onward, in the presumptive olfactory bulbs, whereas kal1.2 transcript is only detected, from 48 h.p.f., in the epithelium of the nasal cavity. The relevance of the zebrafish as an animal model for studying both the function of KAL-1 in normal development and the developmental failure leading to the olfactory defect in Kallmann syndrome, is discussed.  (+info)

A novel mutation of the KAL1 gene in Kallmann syndrome. (6/110)

Kallmann syndrome is defined by the association of hypogonadotropic hypogonadism and anosmia, for which three modes of transmission have been described: X-linked, autosomal recessive and autosomal dominant. The KAL1 gene, responsible for the X-linked form of the disease, has been isolated and its intron-exon organization determined. We report sequence analysis using PCR-direct sequencing method of the entire coding region and splice site junctions of the KAL1 gene in three males with Kallmann syndrome. We found a novel mutation in one case and no mutation in the other two cases. The mutation consisted of a C to T substitution in exon 1 converting codon 66 (CAG) encoding glutamine into a termination codon (TAG)/(Q66X). As a consequence of this mutation, the function of the KAL1 protein consisting of 680 amino acids was severely truncated so as to be consistent with Kallmann syndrome. As only this patient had unilateral renal hypoplasia among the three cases, this would suggest the existence of KAL1 gene mutation in this abnormality.  (+info)

Reactive control of precision grip does not depend on fast transcortical reflex pathways in X-linked Kallmann subjects. (7/110)

It has been shown that subjects maintain grasp stability by automatically regulating grip force in response to loads applied tangentially to a manipulandum held using a precision grip. Signals from cutaneous mechanoreceptors convey the information necessary for both the initiation and scaling of responses. The central neural pathways that support these grip reactions are unknown. However, the latency of the increase in force is similar to that of 'long-latency' transcortical reflexes recorded from muscles following muscle stretch or electrical stimulation of digital nerves. This study assessed the importance of fast transcortical pathways for reactive grip responses by examining these responses in subjects with X-linked Kallmann's syndrome (XKS). Subjects were selected whose corticospinal projection, as assessed by magnetic brain stimulation, is essentially ipsilateral, and in whom the long-latency reflex components following digital nerve stimulation are only found contralateral to the stimulated side. Despite this anomaly of the fast corticospinal pathway, these XKS subjects responded in the same way as control subjects; grip response latencies were similar and responses were appropriately scaled. However, the non-operating hand of these XKS subjects often mirrored the grip force changes of the operating hand. Reflex force mirroring was most marked during the first 50 ms and the force output was always less than 20 % of that of the operating hand. We conclude, firstly, that somatosensory driven precision grip responses that support grasp stability do not depend on fast conducting corticospinal pathways in these subjects and, secondly, that such responses do not use those 'long-latency' reflex pathways probed by cutaneomuscular reflexes elicited by electrical stimulation of digital nerves.  (+info)

A novel mutation of the KAL1 gene in monozygotic twins with Kallmann syndrome. (8/110)

OBJECTIVE: Kallmann syndrome is defined by the association of hypogonadotropic hypogonadism and anosmia. The KAL1 gene is responsible for the X-linked form of Kallmann syndrome. In this study we describe monozygotic twins with Kallmann syndrome due to the same mutation in the KAL1 gene. DESIGN: We studied male monozygotic twins with Kallmann syndrome. METHODS: We analyzed the KAL1 gene using the PCR-direct sequencing method. The twins' mother was examined for the identified mutation. RESULTS: We identified a 14 bp deletion from codon 419 in exon 9 (Pro419del14) in both KAL1 genes of the twins. This was a novel mutation in the KAL1 gene and was responsible for Kallmann syndrome. As Pro419del14 was not detected in the mother of the twins, Pro419del14 was a germline mutation originating from them. These monozygotic twins showed different LH and FSH responses to LH-RH stimulation and different phenotypes such as complications, physiques and psychiatric characters. CONCLUSIONS: We report an identical KAL1 gene mutation in the monozygotic twins with Kallmann syndrome. As these monozygotic twins showed different phenotypes in some respects, we suggest that factors other than mutations in the KAL1gene affect the symptomatic features of Kallmann syndrome.  (+info)

BACKGROUND: Anosmia and hypogonadotrophic hypogonadism are the classic features of X-linked Kallmanns syndrome, a disorder caused by mutations of KAL, a gene expressed during kidney and brain development. About a third of patients have a solitary functioning kidney, but little is known about their renal morbidity. METHODS: We studied seven patients aged 22-35 years with X-linked Kallmanns syndrome and a solitary functioning kidney. RESULTS: Two patients developed significant proteinuria associated with mild to moderate arterial hypertension in the second to third decades of life. In one, proteinuria and renal impairment preceded the appearance of hypertension, and the disorder progressed to chronic renal failure. The remaining five patients had normal plasma creatinine concentrations and no significant proteinuria although four had borderline systolic and/or diastolic hypertension. In two sets of patients from the same kindreds, there was a striking discordance for the occurrence of renal ...

OBJECTIVE: To investigate the etiology of mirror movements in patients with X-linked Kallmanns syndrome (xKS) through statistical analysis of pooled white matter data from structural MR images. BACKGROUND: Mirror movements occur in 85% of xKS patients. Previous electrophysiologic studies have suggested an abnormal ipsilateral corticospinal tract projection in xKS patients exhibiting mirror movements. However, an alternative hypothesis has proposed a functional lack of transcallosal inhibitory fibers. METHODS: T1-weighted brain scans were normalized into stereotaxic space with segregation of gray and white matter to allow comparison of pooled white matter data on a voxel-by-voxel basis using SPM-96 software. Nine xKS patients were compared with two age-matched groups of nonmirroring individuals: nine patients with autosomal Kallmanns syndrome (aKS) and nine age-matched normal (healthy) men. RESULTS: Hypertrophy of the corpus callosum was found in both Kallmanns syndrome groups: the anterior and

The Kallmann syndrome (KS) combines hypogonadotropic hypogonadism (HH) with anosmia. This is a clinically and genetically heterogeneous disease. KAL1, encoding the extracellular glycoprotein anosmin-1, is responsible for the X chromosome-linked recessive form of the disease. Mutations in FGFR1 or FGF8, encoding fibroblast growth factor receptor-1 and fibroblast growth factor-8, respectively, underlie an autosomal dominant form with incomplete penetrance. Finally, mutations in PROKR2 and PROK2, encoding prokineticin receptor-2 and prokineticin-2, have been found in heterozygous, homozygous, and compound heterozygous states. These two genes are likely to be involved both in monogenic recessive and digenic/oligogenic KS transmission modes. Notably, mutations in any of the above-mentioned KS genes have been found in less than 30% of the KS patients, which indicates that other genes involved in the disease remain to be discovered.

Patient Advocate. Janet was diagnosed with Kallmann Syndrome and severe osteoporosis at the age of 48. This was despite many attempts since about age 17 to obtain a diagnosis and appropriate treatment for her symptoms. Although long term treatment was started after a late diagnosis, there was very little information about the syndrome given to her by her doctors.. When the internet became available, in early 2000 she became a member of the English language Yahoo self-help group for people with Kallmann Syndrome and other forms of hypogonadism. Since then, she has been very active in that group. She looks for relevant research papers and explains the syndrome in plain English for people with no scientific/medical background and for whom English may not be their first language. She is also a member of the Yahoo groups for Kallmann Syndrome in German, Italian and Spanish languages. Although she is far less active in those groups, she has posted to them information about this COST Action.. Since ...

in 2 brothers with Kallmann syndrome (KS), which causes inherited GnRH deficiency. Recombinant wild-type SEMA3E protected maturing GnRH neurons from cell death by triggering a plexin D1-dependent (PLXND1-dependent) activation of PI3K-mediated survival signaling. In contrast, recombinant SEMA3E carrying the KS-associated mutation did not protect GnRH neurons from death. In murine models, lack of either SEMA3E or PLXND1 increased apoptosis of GnRH neurons in the developing brain, reducing innervation of the adult median eminence by GnRH-positive neurites. GnRH neuron deficiency in male mice was accompanied by impaired testes growth, a characteristic feature of KS. Together, these results identify ...

In recent years, the rate of infertility has risen to 12.5% in China, among which suffered from Idiopathic Hypogonadotropic Hypogonadism (IHH). IHH, also known as Kallmann Syndrome, is a genetic disorder marked by anosmia and hypogonadism. Abnormalities in various genes may cause a defect in the hypothalamus, causing a deficiency of gonadotropin-releasing hormone (GnRH).

Lawrence Koomson is a doctor living and working in London. On the face of it, he seems no different from any other young man but Lawrence has a secret.. At 33, he has never been through puberty. Hes never had a spot. Hes never had an erection. And hes trapped in the body of a 12-year-old boy.. But this all changed in April 2005, when he began treatment to bring on puberty.. I feel an outsider, different to everyone else, he said before the treatment. People take going through puberty for granted; its just something that happens. For me it has just never happened.. Lawrence has Kallmanns syndrome, a rare condition affecting predominantly men, but also women. A small area in the brain called the hypothalamus cannot work properly causing a hormonal imbalance.. For men like Lawrence, this means his body doesnt produce testosterone, which prevents puberty being triggered. Another characteristic of Kallmanns syndrome is an absent sense of smell.. Having Kallmanns syndrome can lead to ...
The GnRH neurons are unique among the hypothalamic neurons that they originate not in hypothalamus itself, but in the vomeronasal organ of the olfactory bulb and move (in the mouse) between day 10 and 17 of embryonic development into the hypothalamus via the forebrain. When this wandering is impaired, there is not any GnRH synthesis in the hypothalamus due to missing GnRH neurons, a phenomen called Kallmann syndrome, and subsequently the patient undergo hypogonadotrophic hypogonadism.. In a report in Molecular Endocrinology this week Gabriel Di Sante and colleagues from Philadelphia with the help of Canadian coworkers from Ottawa describe in mice another protein involved in this wandering of neurons. They found that the Sirt1 protein is necessary to start the migration of GnRH neurons. Sirt1 is the analogue of sirtuin protein originally found in yeast as Silent regulatory protein and has diverse physiological functions. Sirt1 defective mutants are not viable and die in utero. The paper shows ...

Hypogonadotropic hypogonadism, or the lack of function of the testis or ovary secondary to the lack of pituitary and or hypothalamic trophic hormones, is also sometimes generally termed Kallmanns syndrome. Whether such deficiencies arise from an inborn error of hypothalamic organization and pituitary connection or damage to the hypothalamic pituitary system in prepubertal life, the manifestations of a eunuchoid or apubertal individual with potentially competent pituitary and gonadal function will result. Beyond the achievement of puberty, a similar situation can be recreated by the administration of a long-acting GnRH analog or by conditions of secondary hypothalamic dysfunction such as anorexia nervosa where shutdown of GnRH and its resultant effects cause cessation of gonadal function and even a regression of secondary sexual characteristics. Technically, these conditions are not Kallmanns syndrome but one must recognize the similarities. We have experienced a case of isolated gonadotropin ...
Gonadotropin-releasing hormone (GnRH) controls the pituitary-gonadal axis (1). Embryological studies in various vertebrate species have shown that neuroendocrine GnRH cells (i.e., GnRH1-synthesizing neurons) migrate from the medial part of the nasal epithelium up to the forebrain. In mammals, they migrate in close association with fibers of the vomeronasal and terminal nerves (2, 3). Upon reaching the base of the telencephalon, they penetrate the brain together with the central processes of the terminal nerves, just caudal to the olfactory bulb anlage, and make their way along the medial wall of the cerebral hemisphere to the preoptic/hypothalamic region, where they ultimately settle. Migration of these cells begins during the sixth embryonic week in humans (3). This is also when fibers of the olfactory and terminal nerves first come into contact with the brain, shortly before the emergence of the olfactory bulbs. Kallmann syndrome (KS) is a developmental disorder that combines hypogonadotropic ...

The basic defect leading to hypogonadism in Kallmanns syndrome is an abnormality of hypothalamic GnRH secretion secondary to failure of gonadotropin-releasing hormone(GnRH)-producing neurons to migrate from the olfactory placode to the brain, and to agenesis of the olfactory bulbs. There is therefore a hypothalamic lack of the releasing hormone for gonadotrophins (GnRH ...
Výkal je v praktickom zmysle odpad pre daný organizmus, z ktorého je vylúčený. Pre iné organizmy, či už z oblasti rastlinnej alebo živočíšnej ríše, môže takýto odpad znamenať zdroj živín alebo energie. Kravský výkal vzhľadom na špecifickú konzistenciu a vysoký obsah vody je vo voľnej prírode okamžite atakovaný hmyzom, slúži ako zdroj živín a ako miesto pre nakladenie vajíčok hmyzu. Vyliahnuté larvy sa živia rozkladajúcim sa trusom, ktorý ich vďaka hnilobným procesom navyše udržuje v optimálnej teplote. Skarabeus je chrobák, ktorý vyhľadáva trus bylinožravcov. Samička nakladie larvy do guličky z trusu a následne ju zahrabe do zeme. Vyvíjajúca sa larva sa živí trusom. Podobným príkladom môže byť netopierí trus, ktorý v oblasti výskytu netopierej kolónie znamená nevyhnutné živiny pre šváby, chrobáky a iný hmyz.[2] Trus zvierat sa (okrem vyššie zmienených príkladov z prírody) často používa ľudmi ako hnojivo, či už ...

Background: GnRH neurons originate outside the CNS in the olfactory placode and migrate into the central nervous system, becoming integral components of the hypothalamic-pituitary gonadal axis (HPG).. Objective and hypotheses: We hypothesize that gene(s), whose products are important for pubertal development can be identified via autozygosity mapping together with whole exome sequencing in patients with idiopathic hypogonadotrophic hypogonadism (IHH)/Kallmann Syndrome (KS).. Method: We studied a cohort IHH/KS cases.. Results: Our studies revealed three independent families in which IHH/KS is associated with inactivating CCDC141 variants.. Conclusion: These results indicate that CCDC141 is required for successful migration of GnRH neurons to their final destination in the hypothalamus, and thus establishment of the central part of HPG axis. ...
From UniProt:. Hypogonadotropic hypogonadism 18 with or without anosmia (HH18): A disorder characterized by absent or incomplete sexual maturation by the age of 18 years, in conjunction with low levels of circulating gonadotropins and testosterone and no other abnormalities of the hypothalamic-pituitary axis. In some cases, it is associated with non-reproductive phenotypes, such as anosmia, cleft palate, and sensorineural hearing loss. Anosmia or hyposmia is related to the absence or hypoplasia of the olfactory bulbs and tracts. Hypogonadism is due to deficiency in gonadotropin-releasing hormone and probably results from a failure of embryonic migration of gonadotropin-releasing hormone-synthesizing neurons. In the presence of anosmia, idiopathic hypogonadotropic hypogonadism is referred to as Kallmann syndrome, whereas in the presence of a normal sense of smell, it has been termed normosmic idiopathic hypogonadotropic hypogonadism (nIHH). [MIM:615267]. ...
Hypogonadotropic hypogonadism with or without anosmia. Looking For More References? Other associated nonreproductive phenotypes, such as anosmia, cleft palate, and sensorineural hearing loss, occur with variable frequency. In the presence of anosmia, idiopathic hypogonadotropic hypogonadism has been called Kallmann syndrome KS , whereas in the presence of a normal sense of smell, it has been termed normosmic idiopathic hypogonadotropic hypogonadism nIHH summary by Raivio et al.. Because families have been found to segregate both KS and nIHH, the disorder is here referred to as hypogonadotropic hypogonadism with or without anosmia HH. De Roux et al. There was no gynecomastia. He had a normal sense of smell and no mirror movements of the upper limbs, no abnormal eye movements, no colorblindness, and no renal or craniofacial abnormalities..

Congenital hypogonadotropic hypogonadism (CHH) is a rare disease characterized by delayed/absent puberty and infertility due to an inadequate secretion or action of gonadotrophin-releasing hormone (GnRH), with an otherwise structurally and functionally normal hypothalamic-pituitary-gonadal (HPG) axis. CHH is genetically heterogeneous but, due to the infertility of affected individuals, most frequently emerges in a sporadic form, though numerous familial cases have also been registered. In around 50-60% of cases, CHH is associated with a variety of non-reproductive abnormalities, most commonly anosmia/hyposmia, which defines Kallmann Syndrome (KS) by its presence. Broadly-speaking, genetic defects that directly impact on hypothalamic secretion, regulation, or action of GnRH result in a pure neuroendocrine phenotype, normosmic CHH (nCHH), whereas genetic defects that impact of embryonic migration of GnRH neurons to the hypothalamus most commonly result in KS, though nCHH can also arise. Hence, the ...
Introduction: Up to 10% of patients with congenital hypogonadotropic hypogonadism (HH) may undergo reversal of hypogonadotropism and some of them even attain normal sperm count in adulthood. However, clinical and molecular genetic features of these patients and the triggers leading to reversal of HH are not well understood. We studied whether Finnish reversal variants displayed a common phenotypic or genotypic feature that would predict the clinical course of HH.. Patients and methods: Thirty-two male HH patients with anosmia/hyposmia (Kallmann Syndrome, KS; n=26) or normal sense of smell (nHH; n=6), were enrolled (age range, 18 61 years). The patients were clinically examined, and reversal of HH was assessed after treatment withdrawal. KAL1, FGFR1, FGF8, PROK2, PROKR2, CHD7, WDR11, GNRHR, GNRH1, KISS1R, KISS1, TAC3, TACR3, and LHβ were screened for mutations.. Results: Six HH patients (2 KS, 4 nHH) were verified to have reversal of HH (median age, 23 years; range, 21 39 years). All of them had ...

Clench your left hand into a fist. What happened to your right hand when you did it?. If youre like most people, the answer is nothing. But, surprisingly, not everyone can do this. Some people make mirror movements, where moving one side of the body, particularly the hands, causes the other to move unintentionally. Clench the left fist, and the right one closes too. Doing things like playing the piano or typing are very difficult. In 2002, a Chinese man with the disorder failed to get into the military because he couldnt use the monkey bars.. Young children sometimes make mirror movements but they almost always grow out of it by the age of 10. The only exceptions tend to be people with rare genetic disorders of the nervous system, like Klippel-Feil and Kallmann syndromes. Now, Myriam Srour from the University of Montreal has found that a single faulty gene can cause the condition.. She studied a large French Canadian family with four generations of members who had been making mirror ...
Objectives: Hypogonadism is associated with a higher risk of atherosclerosis and cardiovascular disease, but the mechanisms underlying this association are not yet fully understood. Increased oxidative stress has been associated with development of cardiovascular and cerebrovascular diseases. We aimed to determine serum PON1 activities, an established lipid antioxidant, MDA levels which are end products of lipid peroxidation induced by ROS and thiol groups as an antioxidant for evaluating oxidative stress in patients with hypogonadism before and after replacement therapy.. Design and methods: A total of 18 male patients with untreated idiopathic hypogonadotropic hypogonadism (mean age: 27.4±7.3 years) and age, sex, and weight matched eugonadal healthy subjects (mean age: 32.6±7.2 years) were enrolled in the study as a control group. Serum PON1 activity, MDA and thiol levels were measured according to an enzymatic spectrophotometric method.. Results: Serum MDA and thiol levels were higher and ...

Hypogonadism is a disorder of the reproductive system which results in lack of function of the gonads (ovaries or testes). Hypogonadism is caused by several conditions which may be congenital, acquired, genetic, or malignancies. Hypogonadism may be classified on the basis of etiology and the site causing the defect into primary or secondary hypogonadism. Primary hypogonadism results from defect in the gonads themselves and it has a high level of the gonadotropin hormones FSH and LH. Secondary hypogonadism indicates a defect in the pituitary gland or the hypothalamus and presents with a low level of the gonadotropin releasing hormone, FSH, and LH. Hypogonadism is also associated with low level of testosterone hormone, especially in the males. Genetic mutations that can cause hypogonadism include ANOS 1, SOX10, SEMA3A, IL17RD and FEZF1. Other genes include KISS, GNRNH, and PROK. Hypogonadism must be differentiated from diseases that cause delayed puberty or infertility. The prevalence of ...

The FLT3-TKIs quizartinib and ponatinib are potent type II FLT3 antagonists that bind and inhibit the inactive conformation of FLT3-TK, where the activation loop is in the DFG out position (4, 6). Although they inhibit growth and induce differentiation and apoptosis, as well as induce complete remission in patients with AML, following treatment with the FLT3-TKI, relapse, because of residual AML in which FLT3-ITD activity is persistent, is commonly encountered (2, 4, 6, 14). Several mechanisms of primary resistance to FLT3-TKI have been described in AML BPCs expressing FLT3-ITD. These include the protective effects of stromal niche cells (41), increased levels and activity of FLT3 ligand on FLT3 TK (15, 17), trans-phosphorylation and increased activity of FLT3 by other kinases such as PIM-1 and SYK (42, 43), and the collateral dependency on other important progrowth and prosurvival signaling mechanisms (5, 6, 12, 13). Other studies have focused on developing selective and more potent FLT3-TKIs ...

  • Kallmann syndrome is a form of a group of conditions termed hypogonadotropic hypogonadism . (wikipedia.org)
  • To distinguish it from other forms of hypogonadotropic hypogonadism, Kallmann syndrome has the additional symptom of a total lack of sense of smell (anosmia) or a reduced sense of smell . (wikipedia.org)
  • It is normally difficult to distinguish a case of Kallmann syndrome (KS)/hypogonadotropic hypogonadism (HH) from a straightforward constitutional delay of puberty . (wikipedia.org)
  • This feature distinguishes Kallmann syndrome from most other forms of hypogonadotropic hypogonadism, which do not affect the sense of smell. (medlineplus.gov)
  • A study of Sardinian military recruits found the prevalence of hypogonadism associated with Kallmann syndrome was approximately 1 in 86,000 men. (news-medical.net)
  • Approximately 10-15% of male patients with Kallmann syndrome may be able to have their hypogonadism reversed. (news-medical.net)
  • The Kallmann syndrome (KS) combines hypogonadotropic hypogonadism (HH) with anosmia. (nature.com)
  • Main differential diagnoses are normosmic idiopathic hypogonadotropic hypogonadism and CHARGE syndrome. (nature.com)
  • 1 The syndrome was identified as a clinical entity in 1944 by an American medical geneticist, Kallmann, who carried out a study on the occurrence of hypogonadism accompanied by anosmia in three affected families. (nature.com)
  • 2 He showed the cosegregation of the anosmia and the hypogonadism in all the affected individuals, and therefore established that this syndrome can be hereditary. (nature.com)
  • Pathophysiology of Kallmann syndrome (KS) and normosmic idiopathic hypogonadotropic hypogonadism (nIHH) GnRH is the master controller or 'pilot light' of reproduction. (rarediseases.org)
  • Classic Kallmann syndrome (KS) and idiopathic hypogonadotropic hypogonadism (IHH) are rare genetic conditions that encompass the spectrum of isolated hypogonadotropic hypogonadism. (medscape.com)
  • By definition, either anosmia (lack of sense of smell) or severe hyposmia is present in patients with Kallmann syndrome, in contrast to patients with idiopathic hypogonadotropic hypogonadism, whose sense of smell is normal. (medscape.com)
  • Deficient hypothalamic GnRH secretion underlies the markedly abnormal gonadotropin secretion patterns in most patients with Kallmann syndrome or idiopathic hypogonadotropic hypogonadism. (medscape.com)
  • Some of the genes involved in the pathogenesis of Kallmann syndrome and idiopathic hypogonadotropic hypogonadism have been identified. (medscape.com)
  • [ 3 ] In addition, mutations of the gene encoding chromodomain-helicase DNA-binding protein 7 ( CHD7 ) have been found in some patients with Kallmann syndrome or idiopathic hypogonadotropic hypogonadism, some of whom have features of the CHARGE syndrome (characterized by delayed growth and development, congenital cardiac defects, dysmorphic ears, hearing loss, coloboma of the eyes). (medscape.com)
  • Loss-of-function mutations of critical components of the prokineticin pathway have been implicated in the pathogenesis of Kallmann syndrome and idiopathic hypogonadotropic hypogonadism. (medscape.com)
  • Kallmann syndrome is characterized by hypogonadotrophic hypogonadism and anosmia. (bioone.org)
  • Because classic Kallmann syndrome and idiopathic hypogonadotropic hypogonadism are both congenital disorders, the terms classic and congenital are used interchangeably to refer to Kallmann syndrome and idiopathic hypogonadotropic hypogonadism. (medscape.com)
  • Patients with classic Kallmann syndrome or idiopathic hypogonadotropic hypogonadism may not experience puberty or may experience incomplete puberty and have symptoms associated with hypogonadism. (medscape.com)
  • Notably, patients with Kallmann syndrome or idiopathic hypogonadotropic hypogonadism do not experience hot flashes. (medscape.com)
  • These symptoms are almost universal in men with either Kallmann syndrome or idiopathic hypogonadotropic hypogonadism. (medscape.com)
  • Primary amenorrhea develops in the vast majority of women with classic Kallmann syndrome or idiopathic hypogonadotropic hypogonadism. (medscape.com)
