Robertsonian translocation (RT) is a common cause for male infertility, recurrent pregnancy loss, and birth defects. Studying meiotic recombination in RT-carrier patients helps decipher the mechanism and improve the clinical management of infertility and birth defects caused by RT. Here we present a new method to study spermatogenesis on a single-gamete basis from two RT carriers. By using a combined single-cell whole-genome amplification and sequencing protocol, we comprehensively profiled the chromosomal copy number of 88 single sperms from two RT-carrier patients...

Ciliary disorders, which are also referred to as ciliopathies, are a group of hereditary disorders that result from dysfunctional cilia. The latter are cellular organelles that stick up from the apical plasma membrane. Cilia have important roles in signal transduction and facilitate communications between cells and their surroundings. Ciliary disruption can result in a wide variety of clinically and genetically heterogeneous disorders with overlapping phenotypes. Because cilia occur widespread in our bodies many organs and sensory systems can be affected when they are dysfunctional...

Biomarkers have a wide application in research and clinic, they help to choose the correct treatment for diseases. Recent studies, addressing the vaginal microbiome using next generation sequencing (NGS), reported the involvement of bacterial species in infertility. We compared the vaginal microbiome of idiopathic infertility diagnosed women with that of healthy, non-idiopathic infertile and bacterial vaginosis affected women, to identify bacterial species suitable as biomarkers. Information on microorganisms was obtained from the V3-16S rDNA sequencing of cervical-vaginal fluids of 96 women using the Ion Torrent platform...

CONTEXT: Idiopathic primary ovarian insufficiency (POI) is a major cause of amenorrhea and infertility. POI affects 1% of women before age 40 years, and several genetic causes have been reported. To date, POI has been considered a monogenic disorder. OBJECTIVE: The aim of this study was to identify novel gene variations and to investigate if individuals with POI harbor mutation in multiple loci. PATIENTS AND METHODS: One hundred well-phenotyped POI patients were systematically screened for variants in 19 known POI loci (and potential candidate genes) using next-generation sequencing...

The mammalian oviduct is an essential site for sperm storage, the transport of gametes, fertilization, and embryo development-functions that are aided by cytokines secreted from oviduct epithelial cells (OECs). Aging leads to cellular and organ dysfunction, with infertility associated with advanced maternal age. Few studies have investigated age-dependent changes in the oviduct as a possible cause of infertility, so we compared OECs from young (30-50 months) versus aged (more than 120 months) cattle. Next-generation sequencing was first used to identify age-related differences in gene expression...

Hereditary retinal degenerations encompass a group of genetic diseases characterized by extreme clinical variability. Following next-generation sequencing and autozygome-based screening of patients presenting with a peculiar, recessive form of cone-dominated retinopathy, we identified five homozygous variants [p.(Asp594fs), p.(Gln117*), p.(Met712fs), p.(Ile756Phe), and p.(Glu543Lys)] in the polyglutamylase-encoding gene TTLL5, in eight patients from six families. The two male patients carrying truncating TTLL5 variants also suffered from a substantial reduction in sperm motility and infertility, whereas those carrying missense changes were fertile...

Individuals carrying balanced translocations have a high risk of birth defects, recurrent spontaneous abortions and infertility. Thus, the detection and characterization of balanced translocations is important to reveal the genetic background of the carriers and to provide proper genetic counseling. Next-generation sequencing (NGS), which has great advantages over other methods such as karyotyping and fluorescence in situ hybridization (FISH), has been used to detect disease-associated breakpoints. Herein, to evaluate the application of this technology to detect balanced translocations in the clinic, we performed a parental study for prenatal cases with unbalanced translocations...

Advanced reproductive age is unequivocally associated with increased aneuploidy in human oocytes, which contributes to infertility, miscarriages, and birth defects. The frequency of meiotic chromosome segregation errors in oocytes derived from reproductively aged mice appears to be similar to that observed in humans, but a limitation of this important model system is our inability to accurately identify chromosome-specific aneuploidy. Here we report the validation and application of a new low-pass whole-genome sequencing approach to comprehensively screen chromosome aneuploidy in individual mouse oocytes and blastocysts...

Recently, post-transcriptional gene regulation by microRNAs (miRNAs) has been reported to play a key role during ovary development and differentiation. However, there are no published studies identifying miRNA profiles of human ovarian tissues directly using next-generation sequencing technology. In the human ovary, a total of 762 known and 21 novel human miRNAs were detected, indicating that human ovaries have a complex population of small RNAs. To confirm the miRNA profile in human ovaries, quantitative real-time polymerase chain reaction was used to validate the expression of known miRNAs and novel miRNAs...

The mammalian epididymis is a highly specialized region of the male reproductive tract that is lined with a continuous layer of epithelial cells that display a remarkable level of regionalized secretory and absorptive activity. The luminal environment created by this combined secretory and absorptive activity is directly responsible for promoting the functional maturation of spermatozoa and their maintenance in a quiescent and viable state prior to ejaculation. This study was designed to identify the complement of microRNAs (miRNAs) that are expressed within the mouse epididymal epithelial cells and the maturing populations of spermatozoa...

Preimplantation genetic diagnosis (PGD) is well established method for treatment of genetic problems associated with infertility. Moreover, PGD with next-generation sequencing (NGS) provide new possibilities for diagnosis and new parameters for evaluation in, for example, aneuploidy screening. The aim of the study was to report the successful pregnancy outcome following PGD with NGS as the method for 24 chromosome aneuploidy screening in the case of Robertsonian translocation. Day 3 embryos screening for chromosomal aneuploidy was performed in two consecutive in vitro fertilization (IVF) cycles, first with fluorescent in situ hybridization (FISH), and then with NGS-based protocol...

Male infertility is a multifactorial complex disease with highly heterogeneous phenotypic representation and in at least 15% of cases, this condition is related to known genetic disorders, including both chromosomal and single-gene alterations. In about 40% of primary testicular failure, the etiology remains unknown and a portion of them is likely to be caused by not yet identified genetic anomalies. During the last 10 years, the search for 'hidden' genetic factors was largely unsuccessful in identifying recurrent genetic factors with potential clinical application...

Premature ovarian failure (POF) is a common cause of infertility in women, characterized by amenorrhea, hypoestrogenism, and elevated gonadotropin levels in women under the age of 40. Many genes have been identified over the past few years that contribute to the development of POF. However, few genes have been identified that can explain a substantial proportion of cases of POF. The unbiased approaches of genome-wide association studies and next-generation sequencing technologies have identified several novel genes implicated in POF...

Japanese lawngrass (Zoysia japonica Steud.) is an important warm-season turfgrass that is able to survive in a range of soils, from infertile sands to clays, and to grow well under saline conditions. However, little is known about the molecular mechanisms involved in its resistance to salt stress. Here, we used high-throughput RNA sequencing (RNA-seq) to investigate the changes in gene expression of Zoysia grass at high NaCl concentrations. We first constructed two sequencing libraries, including control and NaCl-treated samples, and sequenced them using the Illumina HiSeq™ 2000 platform...

Mitochondrial DNA (mtDNA) is believed to be both the source and target of reactive oxygen species (ROS), and mtDNA genetic alterations have been reported to be associated with molecular defects in the oxidative phosphorylation (OXPHOS) system. In order to investigate the potentially susceptible mtDNA genetic variants to oligoasthenospermia, we conducted a two-stage study in 921 idiopathic infertile men with oligoasthenospermia and 766 healthy controls using comprehensive molecular analysis. In the screen stage, we used next generation sequencing (NGS) in 233 cases and 233 controls to screen oligoasthenospermia susceptible mitochondrial genetic variants...
