In this review, we would like to summarize gene hunting process in terms of historical aspects from Darwin to now. For this purpose, different approaches and recent developments will be detailed. Summary: Linkage analysis and association studies are the most common methods in use for explaining the genetic background of hereditary diseases and disorders. Although linkage analysis is a relatively old approach, it is still a powerful method to detect disease-causing rare variants using family-based data, particularly for consanguineous marriages. As is known that, consanguineous marriages or endogamy poses a social problem in developing countries, however, this same condition also provides a unique opportunity for scientists to identify and characterize pathogenic variants. The rapid advancements in sequencing technologies and their parallel implementation together with linkage analyses now allow us to identify the candidate variants related to diseases in a relatively short time. Furthermore, we can now go one step further and functionally characterize the causative variant through in vitro and in vivo studies and unveil the variant-phenotype relationships on a molecular level more robustly. Key Messages: Herein, we suggest that the combined analysis of linkage and exome analysis is a powerful and precise tool to diagnose clinically rare and recessively inherited conditions.Publication Metadata only Assessment of miR-1179 As a Potential Biomarker in Juvenile Myoclonic Epilepsy(2022-03-01T00:00:00Z) Süsgün, Seda; Toruntay, Ceyhun; Bayrakoğlu, Alişan; Uslu, Ferda; Yücesan, Emrah; SÜSGÜN, SEDA; TORUNTAY, CEYHUN; BAYRAKOĞLU, ALİŞAN; USLU, FERDA; YÜCESAN, EMRAHPublication Metadata only Tek Basamaklı Ters Transkripsiyon Kantitatif PZR Yönteminin miRNA Ekspresyon Analizleri için Optimizasyonu(2021-08-01T00:00:00Z) Süsgün, Seda; Karacan, İlker; Yücesan, Emrah; SÜSGÜN, SEDA; YÜCESAN, EMRAHObjective: We aimed to investigate and optimize the one step reverse transcription quantitative polymerase chain reaction (RT-qP-CR) method for specific detection and quantitation of two selected microRNA (miRNA)s, namely hsa-miR-145-5p and hsa-miR-146a-5p. Material and Method: RNA was extracted from HEK293T cell line. Primers were designed and experimentally optimized to be compatible with with one step RT-qPCR method for two selected miRNAs. Targeted amplicons were visualized with agarose gel electrophoresis and sequenced using the Sanger method for specificity verification. Results: High specificity of one step RT-qPCR amplification was demonstrated using melt curve and agarose gel electrophoresis analyses for both miRNA targets. It was shown that the earliest cycle threshold (Ct) values were obtained at the annealing tem perature of 54°C. Also, target specificity was confirmed by conventional Sanger sequencing. Conclusion: In this study, one-step RT-qPCR design was optimized for both miRNA targets and target specificity was verified. Our study showed this approach to be a good candidate for miRNA detection and quantitation as a cost-effective alternative method. Furthermore, the approach is highly suitable for research projects as it is both low-cost and fast, involving less hands-on time.Publication Open Access The utility of serum microRNA-93 and microRNA-191 levels for determination of injury severity in adults with multiple blunt trauma(2020-12-01T00:00:00Z) Sogut, Ozgur; Metiner, Merve; Kaplan, Onur; Calık, Mustafa; Cakmak, Sumeyye; Umit, Tugba Betul; Ergenc, Huseyin; Akbas, Fahri; Süsgün, Seda; AKBAŞ, FAHRİ; SÜSGÜN, SEDABACKGROUND: Various scoring systems have been developed to determine the trauma severity and prognosis of patients following multiple blunt trauma (MBT). However, these scoring systems do not provide exactly the desired severity assessment. In recent years, serum concentration of many specific miRNAs, especially for head trauma, has been shown to play an important role in determining the diagnosis, severity and prognosis of injury. To date, however, no studies have investigated serum microRNAs in patients with MBT. Thus, this study measured the expression of miRNA-93 and -191 in the serum of adults with MBT and examined the correlations of Injury Severity Score (ISS) and Revised Trauma Score (RTS) values with serum miRNA-93 and -191 levels in these patients with the aim of predicting trauma severity based on the miRNA levels.METHODS: This prospective case–control study enrolled 50 consecutive adults with MBT and age- and sex-matched 60 healthy controls. The patients were divided into ISS >16 (group 1, major or severe trauma) and ISS ≤16 (group 2, minor or mild-moderate trauma) groups. Serum miRNA-93 and -191 levels were assessed using quantitative real-time reverse transcription-PCR. We evaluated whether the miRNAs were differentially expressed in major and minor MBT patients and determined their utility for assessing the severity of injury.RESULTS: The mean serum miRNA-93 and -191 levels were significantly elevated in the patients compared to the controls and were higher in patients with ISS >16 compared to those with ISS ≤16, although the difference was not significant. In the patients with multitrauma, ISS was significantly, negative and weak correlated with serum miRNA-191 level (rho = –0.320, p = 0.023) but not with the serum miRNA-93 level. No optimal cutoff for the serum miRNA-93 level was found with respect to trauma severity (AUC 0.617, [0.455–0.779]). However, an optimal cutoff value for serum miRNA-191 was identified, with values <1.94 indicating severe trauma (AUC 0.668 [0.511–0.826]; 65.6% sensitivity, 77.8% specificity).CONCLUSION: miRNA-191 and -93 levels were significantly upregulated in multitrauma patients compared to controls. The level of miRNA-191 in conjunction with ISS, but not that of miRNA-93, may be a useful biomarker for determining injury severity in patients with multitrauma.
