Abstract
OBJECTIVE Pituitary stalk interruption syndrome (PSIS) is a rare cause of congenital hypopituitarism. Limited data exist on the gonadotropic status and fertility of adult women with PSIS. Our study aims to describe pubertal development and the evolution of gonadotropic function and fertility in adult women with PSIS. DESIGN A retrospective multicentric French study. METHODS We described gonadotropic function in 56 adult women with PSIS from puberty onward. We compared live birth rates per woman with PSIS with age-matched controls from the large French epidemiological cohort (CONSTANCES). Additionally, we assessed height, body mass index (BMI), blood pressure, other metabolic parameters, and socioeconomic status. RESULTS AND CONCLUSIONS Among 56 women with PSIS, 36 did not experience spontaneous puberty. Of these, 13 underwent ovarian stimulation, resulting in 7 women having a total of 11 children. In the subgroup with spontaneous puberty (n = 20), 4 had a total of 8 pregnancies, while 6 developed secondary gonadotropic deficiency. Women with PSIS had fewer children than controls (0.33 vs 0.63, P = .04). Median height was also lower (160.5 vs 165.0 cm, P < .0001). Although mean blood pressure was lower in women with PSIS compared with controls (111.3/65.9 ± 11.2/8.1 vs 118.7/72.1 ± 10.1/7.7 mmHg, P < .001), there were no significant differences in other metabolic parameters, notably BMI and lipid profile. Employment/academic status was not different in the 2 groups, but fewer women with PSIS were in relationships (42% vs 57.6% in controls, P = .02). The fertility prognosis in patients with PSIS needs optimization. Patients should be informed about the likelihood of declining gonadotropic function over time.

Abstract
The pituitary is an organ of dual provenance: the anterior lobe is epithelial in origin, whereas the posterior lobe derives from the neural ectoderm. The pituitary gland is a pivotal element of the axis regulating reproductive function in mammals. It collects signals from the hypothalamus, and by secreting gonadotropins (FSH and LH) it stimulates the ovary into cyclic activity resulting in a menstrual cycle and in ovulation. Pituitary organogenesis is comprised of three main stages controlled by different signaling molecules: first, the initiation of pituitary organogenesis and subsequent formation of Rathke’s pouch; second, the migration of Rathke’s pouch cells and their proliferation; and third, lineage determination and cellular differentiation. Any disruption of this sequence, e.g., gene mutation, can lead to numerous developmental disorders. Gene mutations contributing to disordered pituitary development can themselves be classified: mutations affecting transcriptional determinants of pituitary development, mutations related to gonadotropin deficiency, mutations concerning the beta subunit of FSH and LH, and mutations in the DAX-1 gene as a cause of adrenal hypoplasia and disturbed responsiveness of the pituitary to GnRH. All these mutations lead to disruption in the hypothalamic–pituitary–ovarian axis and contribute to the development of primary amenorrhea.

Abstract
Several different proteins regulate, directly or indirectly, the production of growth hormones from the pituitary gland, thereby complex genetics is involved. Defects in these genes are related to the deficiency of growth hormones solely, or deficiency of other hormones, secreted from the pituitary gland including growth hormones. These studies can aid clinicians to trace the pattern of the disease between the families, start early treatment and predict possible future consequences. This paper highlights some of the most common and novel genetic anomalies concerning growth hormones, which are responsible for various genetic defects in isolated growth and combined pituitary hormone deficiency disease.

Abstract
The genetic basis for combined pituitary hormone deficiency (CPHD) is complex, involving 30 genes in a variety of syndromic and nonsyndromic presentations. Molecular diagnosis of this disorder is valuable for predicting disease progression, avoiding unnecessary surgery, and family planning. We expect that the application of high throughput sequencing will uncover additional contributing genes and eventually become a valuable tool for molecular diagnosis. For example, in the last 3 years, six new genes have been implicated in CPHD using whole-exome sequencing. In this review, we present a historical perspective on gene discovery for CPHD and predict approaches that may facilitate future gene identification projects conducted by clinicians and basic scientists. Guidelines for systematic reporting of genetic variants and assigning causality are emerging. We apply these guidelines retrospectively to reports of the genetic basis of CPHD and summarize modes of inheritance and penetrance for each of the known genes. In recent years, there have been great improvements in databases of genetic information for diverse populations. Some issues remain that make molecular diagnosis challenging in some cases. These include the inherent genetic complexity of this disorder, technical challenges like uneven coverage, differing results from variant calling and interpretation pipelines, the number of tolerated genetic alterations, and imperfect methods for predicting pathogenicity. We discuss approaches for future research in the genetics of CPHD.

Abstract
INTRODUCTION Mutations in the transcription factor HESX1 can cause isolated growth hormone deficiency (IGHD) or combined pituitary hormone deficiency (CPHD) with or without septo-optic dysplasia (SOD). So far there is no clear genotype-phenotype correlation. PATIENTS AND RESULTS We report four different recessive loss-of-function mutations in three unrelated families with CPHD and no midline defects or SOD. A homozygous p.R160C mutation was found by Sanger sequencing in two siblings from a consanguineous family. These patients presented with ACTH, TSH and GH deficiencies, severe anterior pituitary hypoplasia (APH) or pituitary aplasia (PA) and normal posterior pituitary. The p.R160C mutation was previously reported in a case with SOD, CPHD and ectopic posterior pituitary (EPP). Using exome sequencing, a homozygous p.I26T mutation was found in a Brazilian patient born to consanguineous parents. This patient had evolving CPHD, normal ACTH, APH and normal posterior pituitary (NPP). A previously reported patient homozygous for p.I26T had evolving CPHD and EPP. Finally, we identified compound heterozygous mutations in HESX1, p.[R159W];[R160H], in a patient with PA and CPHD. We showed that both of these mutations abrogate the ability of HESX1 to repress PROP1-mediated transcriptional activation. A patient homozygous for p.R160H was previously reported in a patient with CPHD, EPP, APH. CONCLUSION These three examples demonstrate that HESX1 mutations cause variable clinical features in patients, which suggests an influence of modifier genes or environmental factors on the phenotype.

Abstract
BACKGROUND/AIMS The HESX1 gene is essential in forebrain development and pituitary organogenesis, and its mutations are the most commonly identified genetic cause of septo-optic dysplasia (SOD). The PROP1 gene is involved in anterior pituitary cell lineage specification and is commonly implicated in non-syndromic combined pituitary hormone deficiency (CPHD). We aimed to assess the involvement of HESX1 and PROP1 mutations in a cohort of patients with SOD and CPHD. METHODS Six patients with sporadic SOD and 16 patients with CPHD from 14 pedigrees were screened for mutations in HESX1 and PROP1 genes by exon sequencing. Half of the CPHD patients had variable associated clinical characteristics, such as hearing loss, orofacial cleft, kidney disorder or developmental delay. Novel variants were evaluated in silico and verified in SNP databases. RESULTS A novel heterozygous p.Glu102Gly mutation in the HESX1 gene and a novel homozygous p.Arg121Thr mutation in the PROP1 gene were detected in 2 pedigrees with CPHD. A small previously reported deletion in PROP1 c.301_302delAG was detected in a separate patient with CPHD, in heterozygous state. No mutations were identified in patients with SOD. CONCLUSIONS Our results expand the spectrum of mutations implicated in CPHD. The frequency of 15% of the PROP1 mutations in CPHD was low, likely due to the clinical heterogeneity of the cohort.

Abstract
To investigate the specific mutations in PROP1, POU1F1, LHX3, and HESX1 genes in patients with combined pituitary hormone deficiency (CPHD) in Turkey. Seventy-six patients with CPHD were included in this study. Based on clinical, hormonal, and neuro-radiological data, relevant transcription factor genes were evaluated by Sanger sequencing and multiplex ligation-dependent probe amplification. Total frequency of mutations was 30.9 % in patients with CPHD. Frequency was significantly higher in familial patients (p = 0.001). Three different types of mutations in PROP1 gene (complete gene deletion, c.301-302delAG, a novel mutation; IVS1+2T>G) were found in 12 unrelated patients (21.8 %). Mutations in PROP1 gene were markedly higher in familial than in sporadic cases (58.8 vs. 5.3 %, p < 0.001). Homozygous complete gene deletion was the most common mutation in PROP1 gene (8/12) and was identified in six familial patients. Four different homozygous mutations [p.Q4X, novel mutations; exons 1-2 deletion, p.V153F, p.I244S] were detected in POU1F1 gene. Central precocious puberty was firstly observed in a sporadic-male patient with homozygous POU1F1 (p.I244S) mutation. A homozygous mutation in HESX1 gene (p.R160H) was detected in one patient. This study is the first to investigate specific mutations in CPHD patients in Turkey. Complete deletion in PROP1 gene was the most common mutation encountered in patients with CPHD. We believe that the results of this study will contribute to the establishment of genetic screening strategies in Turkey, as well as to the studies on phenotype-genotype correlations and early diagnosis of CPHD patients.

Identification of HESX1 mutations in Kallmann syndrome. Fertil Steril 2013; 99:1831-7. [PMID: 23465708 DOI: 10.1016/j.fertnstert.2013.01.149] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2012] [Revised: 01/28/2013] [Accepted: 01/29/2013] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To determine whether HESX1 mutations are present in patients with idiopathic hypogonadotropic hypogonadism (IHH)/Kallmann syndrome (KS). DESIGN Polymerase chain reaction-based DNA sequencing was performed on 217 well-characterized IHH/KS patients. Putative missense mutations were analyzed by sorting intolerant from tolerant (SIFT) and Clustal Ω. SETTING Academic medical center. PATIENT(S) Two hundred seventeen patients with IHH/KS and 192 controls. INTERVENTION(S) Deoxyribonucleic acid was extracted from patients and controls; genotype/phenotype comparisons were made. MAIN OUTCOME MEASURE(S) Deoxyribonucleic acid sequence of HESX1, SIFT analysis, and ortholog alignment. RESULT(S) Two novel heterozygous missense mutations (p.H42Y and p.V75L) and previously reported heterozygous missense mutation p.Q6H in HESX1 were identified in 3 of 217 patients (1.4%). All were males with KS. Both p.Q6H and p.H42Y were predicted to be deleterious by SIFT, whereas p.V75L was conserved in 8 of 9 species. No other IHH/KS gene mutations were present. CONCLUSION(S) HESX1 mutations may cause KS in addition to more severe phenotypes. Our findings expand the phenotypic spectrum of HESX1 mutations in humans, thereby broadening its role in development.
