Abstract
RESEARCH QUESTION Premature ovarian insufficiency (POI) is characterised by amenorrhea associated with elevated follicle stimulating hormone (FSH) under the age of 40 years and affects 1-3.7% women. Genetic factors explain 20-30% of POI cases, but most causes remain unknown despite genomic advancements. DESIGN We used whole exome sequencing (WES) in four Iranian families, validated variants via Sanger sequencing, and conducted the Acyl-cLIP assay to measure HHAT enzyme activity. RESULTS Despite ethnic homogeneity, WES revealed diverse genetic causes, including a novel homozygous nonsense variant in SYCP2L, impacting synaptonemal complex (SC) assembly, in the first family. Interestingly, the second family had two independent causes for amenorrhea - the mother had POI due to a novel homozygous loss-of-function variant in FANCM (required for chromosomal stability) and her daughter had primary amenorrhea due to a novel homozygous GNRHR (required for gonadotropic signalling) frameshift variant. WES analysis also provided cytogenetic insights. WES revealed one individual was in fact 46, XY and had a novel homozygous missense variant of uncertain significance in HHAT, potentially responsible for complete sex reversal although functional assays did not support impaired HHAT activity. In the remaining individual, WES indicated likely mosaic Turners with the majority of X chromosome variants having an allelic balance of ∼85% or ∼15%. Microarray validated the individual had 90% 45,XO. CONCLUSIONS This study demonstrates the diverse causes of amenorrhea in a small, isolated ethnic cohort highlighting how a genetic cause in one individual may not clarify familial cases. We propose that, in time, genomic sequencing may become a single universal test required for the diagnosis of infertility conditions such as POI.

Reprod Biol 2022; 22:100673. [PMID: 35901620 DOI: 10.1016/j.repbio.2022.100673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Revised: 07/05/2022] [Accepted: 07/08/2022] [Indexed: 10/16/2022]
Abstract
The abnormal spindle-like, microcephaly-associated (ASPM) gene is a causative gene of autosomal recessive primary microcephaly (MCPH) 5 in humans, which is characterized by a reduction in brain volume. It was previously reported that truncated Aspm proteins in transgenic mice caused major defects in the germline, a severe reduction in ovary weight and the number of follicles accompanied by reduced fertility. However; it remains unknown whether a loss of Aspm induces abnormal ovarian function, resulting in female infertility. In order to assess the ovary function, we examined vaginal smear cytology from the age of 7 weeks to 100 weeks in CAG-mediated Cre-loxP conditional Aspm-/- knockout mice and control female mice. In addition, we evaluated the ovarian size, fibrosis ratio and the number of follicles (primordial, primary, secondary, antral and atretic follicles) in mice from 15 weeks to 100 weeks old by image analyses. Mann-Whitney U-test was used for statistical analysis. The size of the ovary was significantly reduced in Aspm knockout mice at 15-20 weeks, 40-50 weeks and 70-80 weeks old compared with the control mice. Furthermore, at all stages, we found a severe decrease in the number of developing follicles at 10-15 weeks, 40-50 weeks and 70-80 weeks old, accompanied by disrupted cyclic changes of vaginal cytology and an aberrant upregulation of Foxo3, Kitl, and Lhcgr in Aspm knockout female. These results suggested that Aspm might play an important role in the folliculogenesis and estrous cyclicity of the postnatal ovary during maturation and aging.

Abstract
Background Premature ovarian insufficiency (POI) is a heterogeneous clinical syndrome defined by a premature loss of ovarian function that associates menstrual disturbances and hypergonatropic hypogonadism. POI is a major cause of female infertility affecting 1% of women before the age of 40 and up to 0.01% before the age of 20. The etiology of POI may be iatrogenic, auto‐immune or genetic but remains however undetermined in a large majority of cases. An underlying genetic etiology has to be searched in idiopathic cases, particularly in the context of a family history of POI. Methods Whole exome sequencing (WES) was performed in trio in a Belgian patient presenting POI and in her two parents. The patient presented delayed puberty and primary amenorrhea with hypergonadotropic hypogonadism. Results WES identified two novel compound heterozygous truncating mutations in the Newborn oogenesis homeobox (NOBOX) gene, c.826C>T (p.(Arg276Ter)) and c.1421del (p.(Gly474AlafsTer76)). Both mutations were confirmed by Sanger sequencing in the proband's sister who presented the same phenotype. Both variants were pathogenic and very likely responsible for the severe POI in this family. Conclusion We report here for the first time compound heterozygous truncating mutations of NOBOX in outbred patients, generalizing biallelic NOBOX null mutations as a cause of severe POI with primary amenorrhea. In addition, our findings also suggest that NOBOX haploinsufficiency is tolerated.

Abstract
Primary ovarian insufficiency (POI) is a heterogeneous disorder associated with several genes. The majority of cases are still unsolved. Our aim was to identify the molecular diagnosis of a Brazilian cohort with POI. Genetic analysis was performed using a customized panel of targeted massively parallel sequencing (TMPS) and the candidate variants were confirmed by Sanger sequencing. Additional copy number variation (CNV) analysis of TMPS samples was performed by CONTRA. Fifty women with POI (29 primary amenorrhea and 21 secondary amenorrhea) of unknown molecular diagnosis were included in this study, which was conducted in a tertiary referral center of clinical endocrinology. A genetic defect was obtained in 70% women with POI using the customized TMPS panel. Twenty-four pathogenic variants and two CNVs were found in 48% of POI women. Of these variants, 16 genes were identified as BMP8B, CPEB1, INSL3, MCM9, GDF9, UBR2, ATM, STAG3, BMP15, BMPR2, DAZL, PRDM1, FSHR, EIF4ENIF1, NOBOX, and GATA4. Moreover, a microdeletion and microduplication in the CPEB1 and SYCE1 genes, respectively, were also identified in two distinct patients. The genetic analysis of eleven patients was classified as variants of uncertain clinical significance whereas this group of patients harbored at least two variants in different genes. Thirteen patients had benign or no rare variants, and therefore the genetic etiology remained unclear. In conclusion, next-generation sequencing (NGS) is a highly effective approach to identify the genetic diagnoses of heterogenous disorders, such as POI. A molecular etiology allowed us to improve the disease knowledge, guide decisions about prevention or treatment, and allow familial counseling avoiding future comorbidities.

Abstract
BACKGROUND Preeclampsia (PE) is a frequently occurring multisystemic disease affecting ~5% of pregnancies. PE patients may develop HELLP syndrome (haemolysis, elevated liver enzymes, and low platelet), a mother and foetus life-threatening condition. Research into HELLP's genetic origin has been relatively unsuccessful, mainly because normal placental function and blood pressure regulation involve the fine-regulation of hundreds of genes. OBJECTIVE To identify new genes and mutations constituting potential biomarkers for HELLP syndrome. STUDY DESIGN The present case-control study involved whole-exome sequencing of 79 unrelated HELLP women. Candidate variants were screened in a control population constituted by 176 individuals. Stringent bioinformatics filters were used for selecting potentially etiological sequence variants in a subset of 487 genes. We used robust in silico mutation modelling for predicting the potential effect on protein structure. RESULTS We identified numerous sequence variants in genes related to angiogenesis/coagulation/blood pressure regulation, cell differentiation/communication/adhesion, cell cycle and transcriptional gene regulation, extracellular matrix biology, lipid metabolism and immunological response. Five sequence variants generated premature stop codons in genes playing an essential role in placental physiology (STOX1, PDGFD, IGF2, MMP1 and DNAH11). Six variants (ERAP1- p.Ile915Thr, ERAP2- p.Leu837Ser, COMT-p.His192Gln, CSAD-p.Pro418Ser, CDH1- p.Ala298Thr and CCR2-p.Met249Lys) led to destabilisation of protein structure as they had significant energy and residue interaction-related changes. We identified at least two mutations in 57% of patients, arguing in favour of a polygenic origin for the HELLP syndrome. CONCLUSION Our results provide novel evidence regarding PE/HELLP's genetic origin, leading to new biomarkers, having potential clinical usefulness, being proposed.

Abstract
Objective To find the genetic etiology of premature ovarian insufficiency (POI) in a patient with primary amenorrhea and hypergonadotropic hypogonadism. Design Case report. Setting University hospital. Patient(s) A Belgian woman aged 32 years with POI at the age of 17, her parents, and her sister whose POI was diagnosed at age 29. Intervention(s) Analysis of a panel of 31 genes implicated in POI (POIGP) using next-generation sequencing (NGS), Sanger sequencing, and in vitro functional study. Main Outcome Measure(s) Gene variants, family mutational segregation, and in vitro functional impact of the mutant proteins. Result(s) The analysis of the gene panel using NGS identified the presence of two novel follicle-stimulating hormone receptor (FSHR) missense mutations at a compound heterozygous state in the affected patient: c.646 G>A, p.Gly216Arg, and c.1313C>T, p.Thr438Ile. Sanger sequencing showed the presence of each mutation at heterozygous state in the patient’s parents and at heterozygous compound state in the affected sister. Both substituted amino acids (Gly216 and Thr438) were conserved in FSHR of several vertebrate species as well as in other glycoproteins receptors (TSHR and LHCGHR), suggesting a potentially important role in glycoprotein receptor function. An in vitro functional study showed similar results for both variants with more than 90% reduction of their cell surface expression and a 55% reduction of their FSH-induced cyclic adenosine 3′:5′ monophosphate (cAMP) production compared with the wild-type FSHR. Conclusion(s) The analysis of a gene panel of 31 genes implicated in POI allowed us to identify two novel partially inactivating mutations of FSHR that are likely responsible for the POI phenotype of the proband and of her affected sister.

Tang R, Yu Q. Novel variants in women with premature ovarian function decline identified via whole-exome sequencing. J Assist Reprod Genet 2020; 37:2487-2502.

Abstract
PURPOSE To investigate the potential etiologies of premature ovarian insufficiency (POI) and diminished ovarian reserve (DOR). METHODS Fourteen women with sporadic POI and 6 women with DOR were enrolled. We used whole-exome sequencing (WES) and bioinformatics analysis to identify variants in a subset of 599 selected POI candidate genes. The identified genes were subjected to gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment and protein-protein interaction (PPI) network analyses to uncover key genes and pathways. RESULTS Among the 20 patients, 79 heterozygous variants were detected in 49 genes, which were classified as "likely pathogenic" or "variants of uncertain significance" according to the guidelines of the American College of Medical Genetics and Genomics. Most patients (17/20) carried two or more variants. Monoacylglycerol O-acyltransferase 1 mutations were found in six patients, and cytochrome P450 family 26 subfamily B member 1 and Bardet-Biedl syndrome 9 mutations were each found in four patients. Some variants were shared between DOR and POI. Enrichment analyses showed that the identified genes participate in key ovarian processes, such as follicular development, gonadal development, meiosis, Fanconi anemia, homologous recombination, and transforming growth factor β signaling. A PPI network revealed interactions between these proteins. CONCLUSION Premature ovarian function decline may be polygenic, and overlap exists between the genetic backgrounds of DOR and POI. WES and in silico analyses may be a useful clinical tool for etiological diagnosis and risk prediction for high-risk women in the future.

Abstract
Recurrent pregnancy loss (RPL) affects up to 5% of couples. It is believed that genetic factors contribute to the disease's etiology and pathophysiology. Hundreds of genes represent coherent RPL candidates due to mammalian implantation's inherent complexity. Sanger sequencing (direct sequencing) of candidate genes has identified potential RPL causative genes (and variants), including those regulating embryo implantation and pregnancy maintenance. Although this approach is a reliable technique, the simultaneous analysis of large genomic regions is challenging. Next-generation sequencing (NGS) technology has thus emerged as a useful alternative for determining genetic variants and transcriptomic disturbances contributing to monogenic and polygenic diseases pathogenesis. However, interpreting results remains challenging as NGS experiments provide an enormous amount of complex data. The molecular aspects of specific diseases must be fully understood for accurate interpretation of NGS data. This review was thus aimed at describing (for the first time) the most relevant studies involving Sanger and NGS sequencing, leading to the description of variants related to RPL pathogenesis. Successful RPL-related NGS initiatives (including RNAseq-based studies) and future challenges are discussed. We consider that the information given here should be useful for clinicians, scientists, and students to enable a better understanding of RPL etiology. It may also provide a basis for the development of diagnostic/prognostic approaches contributing toward translational medicine.

Abstract
PURPOSE OF REVIEW This manuscript aims to review (for the first time) studies describing NGS sequencing of preeclampsia (PE) women's DNA. RECENT FINDINGS Describing markers for the early detection of PE is an essential task because, although associated molecular dysfunction begins early on during pregnancy, the disease's clinical signs usually appear late in pregnancy. Although several biochemical biomarkers have been proposed, their use in clinical environments is still limited, thereby encouraging research into PE's genetic origin. Hundreds of genes involved in numerous implantation- and placentation-related biological processes may be coherent candidates for PE aetiology. Next-generation sequencing (NGS) offers new technical possibilities for PE studying, as it enables large genomic regions to be analysed at affordable cost. This technique has facilitated the description of genes contributing to the molecular origin of a significant amount of monogenic and complex diseases. Regarding PE, NGS of DNA has been used in familial and isolated cases, thereby enabling new genes potentially related to the phenotype to be proposed. For a better understanding of NGS, technical aspects, applications and limitations are presented initially. Thereafter, NGS studies of DNA in familial and non-familial cases are described, including pitfalls and positive findings. The information given here should enable scientists and clinicians to analyse and design new studies permitting the identification of novel clinically useful molecular PE markers.

Abstract
Premature ovarian insufficiency (POI) is a highly heterogeneous ovarian disorder. Genetic factors account for the cause of POI. We aimed to analyze the genetic alterations in two affected sisters diagnosed with POI and their parents from a highly consanguineous Chinese Han family. Whole-exome sequencing was performed, and bioinformatics analysis was used to determine the potential genetic cause of POI in this family. A SYCE1 deletion was verified by Sanger sequencing. A homozygous deletion in SYCE1 was harbored by the proband and her affected sister, whereas both parents had heterozygous deletions. There were distinct differences in the amino acid sequences between wild-type and SYCE1 deletion. Domain analysis and 3D structural analysis of the SYCE1 deletion was also performed to evaluate the potential impact and pathogenicity of POI. The SYCE1 domain structure was truncated. Additionally, the 3D structure showed that the SYCE1 deletion changed the shape of the protein compared with that of wild-type SYCE1. This study revealed a novel SYCE1 deletion. This SYCE1 deletion may be the cause of POI. Genetic counseling for POI is helpful for researchers and clinicians to identify the mode of genetic inheritance for SYCE1 deletion in POI pathology.

Abstract
Endocrine and paracrine signals can be key regulators of ovarian physiology. The oocyte secretes growth factors which directly induce follicular development by a complex paracrine signalling process, and the transforming growth factorβ (TGF-β) superfamily has a pivotal role in this process. The bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9) genes are relevant members of the TGF-β superfamily that encode proteins secreted by the oocytes into the ovarian follicles, where they contribute to creating an environment supporting follicle selection and growth. Their main functions include regulating cellular proliferation/differentiation, follicular survival/atresia, and oocyte maturation. Recent functional studies have validated genetic factors (Progesterone receptor membrane component 1 (PGRMC1)), Fragile X mental retardation 1 (FMR1, GDF9 and BMP15) as being causative of primary ovarian insufficiency (POI), BMP15/GDF9 gene variants were found to have a high incidence on the POI phenotype. This review considers the most recent research regarding the role of BMP15 and GDF9 in the genetic control of follicular development, paying special attention to the pathogenesis of POI.

Abstract
A thorough understanding of epigenetics regulatory mechanisms of premature ovarian failure (POF) is still lacking. Here, we found that cyclophosphamide induced significantly decrease in α-Klotho (Kl) expression in mouse ovarian granulosa cells (mOGCs), suggesting that cyclophosphamide inhibited Kl expression. Cyclophosphamide also significantly accelerated ageing and led to a decline in the pregnancy rate of C. elegans. We subsequently noted that the pathological condition exhibited by Kl-/- mice was similar to that observed in cyclophosphamide-induced POF mice. Furthermore, the mOGCs in both types of mice showed significant signs of oxidative stress damage, including decreased SOD and ATP, increased ROS levels. Detailed analyses revealed that the decreased Kl expression led to the reduced expression of autophagy-related proteins in mOGCs, which resulted in decreased autophagy activity. Finally, we found that cyclophosphamide attenuated the autophagy function of mOGCs via upregulating microRNA-15b expression, which silenced the endogenous Kl mRNA expression and stimulated the activity of the downstream TGFβ1/Smad pathway. Therefore, we demonstrated that Kl was one of the key inhibitory factors in the development of POF. It elucidated the underlying epigenetic regulatory mechanism, whereby cyclophosphamide-dependent microRNA-15b inhibited Kl expression, leading to the reduced ability of mOGCs to induce autophagy and ROS scavenging, ultimately causing POF.

Abstract
Background Human reproductive disorders consist of frequently occurring dysfunctions including a broad range of phenotypes affecting fertility and women’s health during pregnancy. Several female-related diseases have been associated with hypofertility/infertility phenotypes, such as recurrent pregnancy loss (RPL). Other occurring diseases may be life-threatening for the mother and foetus, such as preeclampsia (PE) and intra-uterine growth restriction (IUGR). FOXD1 was defined as a major molecule involved in embryo implantation in mice and humans by regulating endometrial/placental genes. FOXD1 mutations in human species have been functionally linked to RPL’s origin. Methods FOXD1 gene mutation screening, in 158 patients affected by PE, IUGR, RPL and repeated implantation failure (RIF), by direct sequencing and bioinformatics analysis. Plasmid constructs including FOXD1 mutations were used to perform in vitro gene reporter assays. Results Nine non-synonymous sequence variants were identified. Functional experiments revealed that p.His267Tyr and p.Arg57del led to disturbances of promoter transcriptional activity (C3 and PlGF genes). The FOXD1 p.Ala356Gly and p.Ile364Met deleterious mutations (previously found in RPL patients) have been identified in the present work in women suffering PE and IUGR. Conclusions Our results argue in favour of FOXD1 mutations’ central role in RPL, RIF, IUGR and PE pathogenesis via C3 and PlGF regulation and they describe, for the first time, a functional link between FOXD1 and implantation/placental diseases. FOXD1 could therefore be used in clinical environments as a molecular biomarker for these diseases in the near future.

Abstract
Background Premature ovarian insufficiency (POI) leads to early loss of ovarian function in women aged < 40 years and is highly heterogeneous in etiology. The genetic etiology of this disorder remains unknown in most women with POI. Methods Whole-exome sequencing (WES) was used to analyze genetic factors within a Chinese POI pedigree. Bioinformatic analysis was applied to identify the potential genetic cause, and Sanger sequencing confirmed the existence of a mutation within the pedigree. A minigene assay was performed to validate the effect of the mutation on pre-mRNA splicing. Results A novel heterozygous missense mutation in HFM1 (c.3470G > A) associated with POI was identified by whole-exome sequencing. This mutation was heterozygous in the affected family members and was absent in the unaffected family members. In silico analysis predicted that the mutation was potentially pathogenic. Bioinformatic splice prediction tools revealed that the mutation was very likely to have a strong impact on splice site function. Results of the minigene assay revealed that the mutation changed the mRNA splicing repertory. Conclusions The missense mutation of the HFM1 gene (c.3470G > A) may be a cause of POI. The mutation altered mRNA splicing in cells. This study can provide geneticists with deeper insight into the pathogenesis of POI and aid clinicians in making early diagnoses in affected women.

Abstract
CONTEXT Primary ovarian insufficiency (POI) is a cause of female infertility. However, the genetic etiology of this disorder remains unknown in most patients with POI. OBJECTIVE To investigate the genetic etiology of idiopathic POI. PATIENTS AND METHODS We performed whole-exome sequencing of 11 families with idiopathic POI. To gain insights into the potential mechanisms associated with this mutation, we generated two mouse lines via clustered regularly interspaced short palindromic repeats/Cas9 technology. RESULTS A pathogenic homozygous missense mutation (c.149A>G; p.Asp50Gly) in the POLR3H gene in two unrelated families was identified. Pathogenic mutations in this subunit have not been associated with human disorders. Loss-of-function Polr3h mutation in mice caused early embryonic lethality. Mice with homozygous point mutation (Polr3hD50G) were viable but showed delayed pubertal development, characterized by late first estrus or preputial separation. The Polr3hD50G female and male mice showed decreased fertility later in life, associated with small litter size and increased time to pregnancy or to impregnate a female. Polr3hD50G mice displayed decreased expression of ovarian Foxo3a and lower numbers of primary follicles. CONCLUSION Our manuscript provides a case of POI caused by missense mutation in POLR3H, expanding the knowledge of molecular pathways of the ovarian function and human infertility. Screening of the POLR3H gene may elucidate POI cases without previously identified genetic causes, supporting approaches of genetic counseling.

Abstract
PURPOSE Primary ovarian insufficiency (POI) is a frequent disorder that affects ~1% of women under 40 years of age. POI, which is characterized by the premature depletion of ovarian follicles and elevated plasma levels of follicle-stimulating hormone (FSH), leads to infertility. Although various etiological factors have been described, including chromosomal abnormalities and gene variants, most cases remain idiopathic. The aim of the present study was to identify and validate functionally new sequence variants in ATG (autophagy-related genes) leading to POI. METHODS We have reanalyzed, in silico, the exome sequencing data from a previously reported work performed in 69 unrelated POI women. Functional experiments using a classical hallmark of autophagy, the microtubule-associated protein 1 light chain 3β (LC3), were then used to link these genes to this lysosomal degradation pathway. RESULTS We venture a functional link between ATG7 and ATG9A variants and POI. We demonstrated that variant ATG7 and ATG9A led to a decrease in autophagosome biosynthesis and consequently to an impairment of autophagy, a key biological process implicated in the preservation of the primordial follicles forming the ovarian reserve. CONCLUSION Our results unveil that impaired autophagy is a novel pathophysiological mechanism involved in human POI.

Abstract
Recurrent pregnancy loss (RPL) affects up to 5% of couples. It is believed that genetic factors contribute to the disease's etiology and pathophysiology. Hundreds of genes represent coherent RPL candidates due to mammalian implantation's inherent complexity. Sanger sequencing (direct sequencing) of candidate genes has identified potential RPL causative genes (and variants), including those regulating embryo implantation and pregnancy maintenance. Although this approach is a reliable technique, the simultaneous analysis of large genomic regions is challenging. Next-generation sequencing (NGS) technology has thus emerged as a useful alternative for determining genetic variants and transcriptomic disturbances contributing to monogenic and polygenic diseases pathogenesis. However, interpreting results remains challenging as NGS experiments provide an enormous amount of complex data. The molecular aspects of specific diseases must be fully understood for accurate interpretation of NGS data. This review was thus aimed at describing (for the first time) the most relevant studies involving Sanger and NGS sequencing, leading to the description of variants related to RPL pathogenesis. Successful RPL-related NGS initiatives (including RNAseq-based studies) and future challenges are discussed. We consider that the information given here should be useful for clinicians, scientists, and students to enable a better understanding of RPL etiology. It may also provide a basis for the development of diagnostic/prognostic approaches contributing toward translational medicine.

Abstract
Primary ovarian insufficiency (POI) is a frequently occurring disease affecting women under 40 years old. Recently, we have analyzed unrelated POI women via whole exome sequencing (WES) and identified NOTCH2 mutations underlying possible functional effects. The present study involved reanalyzing of WES assays. We used in the KGN granulosa-like cell model, a synthetic gene reporter construct driving luciferase gene expression to assess the functional effects of five NOTCH2 mutations identified in POI patients. We found that NOTCH2-p.Ser1804Leu, p.Ala2316Val, and p.Pro2359Ala mutations had a functional impact on the protein's transcriptional activity. The results have demonstrated for the first time that NOTCH2 mutations contribute to POI etiology. We therefore recommend sequencing NOTCH2's open reading frame in large panels of POI patients to establish an accurate genotype-phenotype correlation. We cannot rule out the fact that patients affected by Alagille syndrome carrying NOTCH2 mutations may suffer ovarian dysfunction.

Abstract
OBJECTIVE To investigate the genetic cause of non-syndromic ovarian dysfunction in a patient from a consanguineous family. METHODS This study examined a patient with irregular menstrual cycles and abnormal oocytes. The patient had undergone irregular hormone replacement therapy over 3 years to adjust the menstrual cycle and improve ovarian function. Prior to ovarian stimulation in our hospital, 3 months of androgen and regular hormone therapy were used as an intervention method. No follicular development was detected in the subsequent three cycles using letrozole treatment. The patient then received a constantly adjusted dose of menotropins, but produced only one oocyte. RESULTS Whole-exome sequencing analysis identified the first homozygous POLG mutation (c.2890C > T; p.R964C) associated with ovarian dysfunction. Sanger sequencing was used to validate. In silico analysis suggested that the p.R964C mutation was pathogenic. Conservation analysis demonstrated that R964 was an important site for the DNA polymerase function of POLG. CONCLUSIONS Biallelic mutations in POLG may be associated with ovarian dysfunction. This study has improved our understanding of POLG-related genetic mutations in ovarian dysfunction, and the mode of inheritance of certain sequence variants. This information will assist genetic counseling and precision medicine in the future.

Two rare loss-of-function variants in the STAG3 gene leading to primary ovarian insufficiency. Eur J Med Genet 2018; 62:186-189. [PMID: 30006057 DOI: 10.1016/j.ejmg.2018.07.008] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2018] [Revised: 05/29/2018] [Accepted: 07/09/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND/AIM Primary ovarian insufficiency (POI) is characterized by primary or secondary amenorrhea, infertility, low estradiol levels, and increased gonadotropin levels. Most cases of POI remain unsolved even after exhaustive investigation. Here, we performed a targeted massively parallel sequencing to identify the genetic diagnosis of primary ovarian insufficiency (POI) in a Brazilian patient. PATIENT AND METHODS An adopted 21-year-old Brazilian woman with isolated POI was selected. A custom SureSelectXT DNA target enrichment panel was designed and sequenced on an Illumina NextSeq 500 sequencer. The variants were confirmed using Sanger sequencing. RESULTS Two rare heterozygous pathogenic variants in the STAG3 gene were identified in our patient. An unpublished 1-bp duplication c.291dupC (p.Asn98Glnfs*2) and one stop codon variant c.1950C > A (p.Tyr650*) were identified in the STAG3 gene. Both undescribed heterozygous variants were absent in the public databases [1000Genomes, Exome Aggregation Consortium (ExAC), National Heart, Lung, and Blood Institute Exome Variant Server (NHLBI/EVS), database of Single Nucleotide Polymorphisms (dbSNP), Genome Aggregation Database (gnomAD)], and Online Archive of Brazilian Mutations (ABraOM) databases. Moreover, neither heterozygous variants were found in 400 alleles from fertile Brazilian women screened by Sanger sequencing. The parents' DNA was not available to segregate these variants. CONCLUSION Our results suggested that POI is caused by pathogenic compound heterozygous variants in the STAG3 gene, supporting the key role of the STAG3 gene in the etiology of primary ovarian insufficiency.

Abstract
Background To dissect the genetic alteration in two sisters with premature ovarian insufficiency (POI) from a consanguineous family. Methods Whole-exome sequencing technology was used in the POI proband, bioinformatics analysis was carried out to identify the potential genetic cause in this pedigree. Sanger sequencing analyses were performed to validate the segregation of the variant within the pedigree. In silico analysis was also used to predict the effect and pathogenicity of the variant. Results Whole-exome sequencing analysis identified novel and rare homozygous mutation associated with POI, namely mutation in FIGLA (c.2 T > C, start codon shift). This homozygous mutation was also harbored by the proband’s sister with POI and was segregated within the consanguineous pedigree. The mutation in the start codon of the FIGLA gene alters the open reading frame, leading to a FIGLA knock-out like phenotype. Conclusions Biallelic mutations in FIGLA may be the cause of POI. This study will aid researchers and clinicians in genetic counseling of POI and provides new insights into understanding the mode of genetic inheritance of FIGLA mutations in POI pathology.
