Abstract:
Merging Sanger sequences is frequently needed during the gene cloning process. In this study, we provide a Python script that is able to assemble multiple overlapping Sanger sequences. The script utilizes the overlapping regions within the tandem Sanger sequences to merge the Sanger sequences. The results demonstrate that the script can produce the merged sequence from the input Sanger sequences in a single run. The script offers a simple and free method for merging Sanger sequences and is useful for gene cloning.

Abstract:
Sanger sequencing, the traditional “gold standard” for mutation detection, has been wildly used in genetic testing of pulmonary artery hypertension (PAH). However, with the advent of whole-exome sequencing (WES), few studies have compared the accuracy of WES and Sanger sequencing in routine genetic testing of PAH. PAH individuals were enrolled from Fu Wai Hospital and Shanghai Pulmonary Hospital. WES was used to analyze DNA samples from 120 PAH patients whose bone morphogenetic protein receptor type 2 (BMPR2) mutation statuses had been previously studied using Sanger sequencing. The Sanger sequencing and WES agreement was 98.3% (118/120) with near-perfect agreement (κ coefficient = 0.848). There was no significant difference between the two methods on the McNemar–Bowker test ( P > 0.05). Twenty-one BMPR2 mutation carriers and 99 non-carriers were detected by Sanger sequencing. Among the 21 BMPR2 carriers detected by Sanger sequencing, one variant (c.1040 T > A) was not found by WES. Among the 99 BMPR2 non-carriers, WES detected an extra mutation carrier (c.76 + 1 G > C) missed by Sanger sequencing. Both false-positive and false-negative results were highly conserved and were re-analyzed by Sanger sequencing. WES improved the accuracy of Sanger sequencing and detected 1% (1/99) false-positive and 4.8% (1/21) false-negative results of Sanger sequencing. No false-positive and false-negative results of WES were identified in our analysis. WES is non-inferior to Sanger sequencing and may play a more important role in genetic testing of PAH patients in the future.

Abstract:
Abstract BACKGROUND Next-generation sequencing (NGS) data are used for both clinical care and clinical research. DNA sequence variants identified using NGS are often returned to patients/participants as part of clinical or research protocols. The current standard of care is to validate NGS variants using Sanger sequencing, which is costly and time-consuming. METHODS We performed a large-scale, systematic evaluation of Sanger-based validation of NGS variants using data from the ClinSeq® project. We first used NGS data from 19 genes in 5 participants, comparing them to high-throughput Sanger sequencing results on the same samples, and found no discrepancies among 234 NGS variants. We then compared NGS variants in 5 genes from 684 participants against data from Sanger sequencing. RESULTS Of over 5800 NGS-derived variants, 19 were not validated by Sanger data. Using newly designed sequencing primers, Sanger sequencing confirmed 17 of the NGS variants, and the remaining 2 variants had low quality scores from exome sequencing. Overall, we measured a validation rate of 99.965% for NGS variants using Sanger sequencing, which was higher than many existing medical tests that do not necessitate orthogonal validation. CONCLUSIONS A single round of Sanger sequencing is more likely to incorrectly refute a true-positive variant from NGS than to correctly identify a false-positive variant from NGS. Validation of NGS-derived variants using Sanger sequencing has limited utility, and best practice standards should not include routine orthogonal Sanger validation of NGS variants.

Abstract:
Background. BRAF exon 15 p.V600E (BRAF V600E) mutation has been established as an important molecular marker for papillary thyroid carcinoma diagnosis by ultrasound-guided fine-needle aspiration biopsy (FNAB). Sanger sequencing is the gold standard for detecting BRAF V600E mutations but fails to identify low-frequency mutations. However, droplet digital PCR (ddPCR) is a popular new method for detecting low-frequency mutations. Here, we compare the efficiency of droplet digital PCR (ddPCR) and Sanger sequencing for detection of the BRAF V600E mutation in thyroid fine-needle aspiration (FNA) samples. Methods. Thyroid fine-needle aspiration samples from 278 patients with 310 thyroid nodules were collected. Sanger sequencing and ddPCR were conducted to detect the BRAF V600E mutation. Results. The BRAF V600E mutation was found in 94 nodules (30.32%) by ddPCR and 40 nodules (12.90%) by Sanger sequencing in 310 FNA samples. A total of 119 nodules were confirmed PTC by postsurgical pathology. Among which the BRAF mutation was found in 80 (67.23%) nodules by ddPCR and 31 (26.05%) by Sanger sequencing. All nodules carrying the mutation detected by Sanger sequencing (SS+) were verified by ddPCR (ddPCR+). Also, all nodules with no mutation detected by ddPCR were interpreted as wild-type by Sanger sequencing (SS−). In addition. Almost all SS+/ddPCR + nodules (95.00%; 38/40) and SS−/ddPCR + nodules (100.00%; 54/54) displayed a BRAF mutation rate of >5% and <15%, respectively, indicating easy misdetection by Sanger sequencing when the mutation rate is between 5 and 15%. Conclusion. ddPCR has higher sensitivity than Sanger sequencing and we propose ddPCR as a supplement to Sanger sequencing in molecular testing of BRAF using FNAB samples.

Abstract:
Determining the exact type of epidermal growth factor receptor (EGFR) exon 20 insertion (ex20ins) mutation in lung cancer has become important. We found that not all ex20ins mutations reported by cobas EGFR test v2 could be validated by Sanger sequencing even using surgical specimens with high tumor contents. This study aimed to validate the ex20ins results reported by the cobas test and to determine whether there were clinicopathological factors associated with aberrant cobas ex20ins report. In total, 123 cobas-reported cases with ex20ins were retrospectively collected and validated by Sanger sequencing and Idylla assay. Clinicopathological features between ex20ins cobas+/Sanger+ group (n = 71) and cobas+/Sanger− group (n = 52) were compared. The Idylla assay detected ex20ins in 82.6% of cobas+/Sanger+ cases but only in 4.9% of cobas+/Sanger− cases. The cobas+/Sanger− group was significantly associated with higher tumor contents, poorly differentiated patterns, tumor necrosis, and a lower internal control cycle threshold value reported by the Idylla which suggesting the presence of increased EGFR gene copy numbers. EGFR fluorescence in situ hybridization (FISH) revealed the majority of cobas+/Sanger− group had EGFR high copy number gain (16%) or amplification (76%) according to the Colorado criteria. Among cases reported to have concomitant classic EGFR and ex20ins mutations by the cobas, the classic EGFR mutations were all detected by Sanger sequencing and Idylla, while the ex20ins mutations were undetected by Sanger sequencing (0%) or rarely reported by Idylla assay (3%). FISH revealed high EGFR copy number gain (17.9%) and amplification (79.5%) in cases reported having concomitant classic EGFR and ex20ins mutations by the cobas. This study demonstrated an unusually high frequency of EGFR amplification in cases with aberrant cobas ex20ins report which could not be validated by Sanger sequencing or Idylla assay. Ex20ins reported by the cobas test should be validated using other methods especially those reported having concomitant ex20ins and classic EGFR mutations.

Abstract:
Sanger community in North Sulawesi has one type of sacred food called Kue Adat Tamo. The food has become medium and symbol of Sanger community's religious worship. The sacredness of Tamo Traditional Cake is internalized and expressed in an annual Tulude ritual forming their inclusive social religious identity. Therefore, this paper aims to answer the ontological question about the understanding of Sanger community in Tuma towards the sacredness of Tamo Traditional Cake that becomes their collective expression and inclusiveness. To answer this question, the research was conducted using a qualitative approach and the type of ethnographic research as well as data collection techniques through interviews and observations carried out in Tuma Sanger Village. The result of the study indicates that the sacredness of Tamo Traditional Cake lies in the collective admiration and respect of Tuma community in Sanger for Ghenggonalangi which is symbolically expressed in the community's annual thanksgiving party known as Tulude. Based on these findings, the main argument of this paper is that the sacredness of Tamo Traditional Cake is rooted in the acculturation of religious culture and the social reality of Tuma Sanger community.

Abstract:
8596 Background: Detection of BRAF V600 mutations is currently a prerequisite for approved use of vemurafenib in patients with metastatic melanoma. The cobas 4800 BRAF V600 Mutation Test (Roche Molecular Diagnostics), a PCR-based assay approved to aid in selecting patients for vemurafenib therapy, primarily detects V600E. It is also reported to detect V600K, which has been associated with vemurafenib response as well. We compared the mutation detection rate of the cobas assay with that of Sanger sequencing. Methods: 125 de-identified FFPE tissues submitted for BRAF mutation analysis that all showed histologically-confirmed melanoma were tested. BRAF mutations were detected using both the cobas kit and bidirectional Sanger sequencing using BigDye kits (Applied Biosystems). DNA was extracted from 5-um sections without macrodissection using the cobas DNA extraction kit (for the cobas test) or from 5-10-um sections using Agencourt extraction kits (Beckman Coulter) following macrodissection. Results: The two methods showed agreement in 104/125 (83.2%) of cases (Table). Sanger sequencing detected V600 dinucleotide mutations in 9 samples that were negative by the cobas assay. Sanger sequencing produced no results in 10 cases owing to suboptimal PCR, including 2 that were positive by the cobas assay. The cobas assay produced 2 invalid results, including 1 that was positive for V600E by Sanger.The cobas assay detected 7/11 V600K mutations. Conclusions: Overall agreement between cobas and Sanger sequencing was 83.2%. The Sanger method had higher analytic sensitivity, resulting in nine additional V600 mutations not called by cobas compared to the two seen by cobas but not Sanger sequencing. Thus, 16% (9/57) more patients would be identified as candidates for vemurafenib therapy using the Sanger method. [Table: see text]

Abstract:
Abstract BACKGROUND Dideoxy-based chain termination sequencing developed by Sanger is the gold standard sequencing approach and allows clinical diagnostics of disorders with relatively low genetic heterogeneity. Recently, new next generation sequencing (NGS) technologies have found their way into diagnostic laboratories, enabling the sequencing of large targeted gene panels or exomes. The development of benchtop NGS instruments now allows the analysis of single genes or small gene panels, making these platforms increasingly competitive with Sanger sequencing. METHODS We developed a generic automated ion semiconductor sequencing work flow that can be used in a clinical setting and can serve as a substitute for Sanger sequencing. Standard amplicon-based enrichment remained identical to PCR for Sanger sequencing. A novel postenrichment pooling strategy was developed, limiting the number of library preparations and reducing sequencing costs up to 70% compared to Sanger sequencing. RESULTS A total of 1224 known pathogenic variants were analyzed, yielding an analytical sensitivity of 99.92% and specificity of 99.99%. In a second experiment, a total of 100 patient-derived DNA samples were analyzed using a blind analysis. The results showed an analytical sensitivity of 99.60% and specificity of 99.98%, comparable to Sanger sequencing. CONCLUSIONS Ion semiconductor sequencing can be a first choice mutation scanning technique, independent of the genes analyzed.

Abstract:
Background: BRAF V600E mutation has been confirmed as a significant molecular indicator for the diagnosis and prognosis of papillary thyroid carcinoma (PTC). Sanger sequencing is the recognized approach for BRAF V600E mutation analysis, yet it is not proficient at detecting mutations that occur at low frequencies, especially in thyroid fine needle aspiration (FNA) specimens. This study aimed to evaluate the diagnostic value of Competitive Allele-Specific TaqMan PCR (castPCR) as a new reliable method for BRAF V600E mutation test in thyroid FNA specimens compared to Sanger sequencing. Methods: Thirty patients with thyroid nodules were enrolled prospectively at Dharmais Cancer Hospital Jakarta from 2013–2014. The BRAF V600E mutation was analyzed from FNA specimens using castPCR and Sanger Sequencing methods. The sensitivity and specificity of those methods were compared with routine diagnostic histopathological examination as a gold standard for PTC assessment.Results: A total of 66.6% (20/30) cases were confirmed as PTC by postsurgical histopathological examination. Among these, the BRAF V600E mutation was found in 60.0% (12/20) by castPCR and 40.0% (8/20) by Sanger sequencing. Neither castPCR nor Sanger sequencing detected BRAF V600E mutation in other nodular thyroid diseases. The sensitivity and specificity of castPCR were 60.0% and 100.0%, while Sanger sequencing was 40.0% and 100.0%, respectively. Conclusions: This study indicated that castPCR has a higher sensitivity for the BRAF V600E mutation test than Sanger Sequencing, especially in samples with a low abundance of mutant alleles. A sensitive, rapid, and easy castPCR method is reliable for evaluating BRAF V600E mutation and can improve PTC preoperative diagnosis in clinical settings.
