Next-generation Sequencing

98.9K
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features....

Reliability and Validity01:29

Reliability and Validity

14.1K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Leaky Scanning02:28

Leaky Scanning

5.7K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Chromatin Position Affects Gene Expression02:35

Chromatin Position Affects Gene Expression

25.0K
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences  access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area. 
Topologically Associated Domains (TADs)
The 3-dimensional positioning of chromatin in the nucleus influences the...

Cis-regulatory Sequences02:02

Cis-regulatory Sequences

11.9K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Area of Science:

  • Molecular genetics
  • Diagnostic testing
  • Genomic sequencing

Background:

  • European laboratories utilize diverse methods for CFTR gene analysis to detect cystic fibrosis (CF) and CFTR-related disorders (CFTR-RDs).
  • Next-generation sequencing (NGS) is prevalent in diagnostics, with CE-IVD marking essential for European in vitro diagnostic tests.
  • A multicenter study involving three specialized European labs assessed the Multiplicom CFTR MASTR Dx kit for CE-IVD certification.

Purpose of the Study:

  • To evaluate the performance of the Multiplicom CFTR MASTR Dx kit.
  • To determine the kit's suitability for CE-IVD certification in Europe.
  • To assess the kit's utility in routine molecular genetic analysis of the CFTR gene.

Main Methods:

  • 164 samples, previously analyzed by reference methods, were re-sequenced using the Illumina MiSeq NGS platform.
  • Sequencing data were processed using two distinct bioinformatic pipelines.
  • Annotated variants were compared against established reference data for performance evaluation.

Main Results:

  • The Multiplicom CFTR MASTR assay achieved analytical sensitivity, specificity, and accuracy rates exceeding 99%.
  • The assay can detect various CFTR mutations within a single workflow.
  • The kit simplifies the diagnostic process.

Conclusions:

  • The CFTR MASTR Dx kit demonstrates high analytical performance.
  • Its efficiency and accuracy make it well-suited for routine cystic fibrosis diagnostics.
  • The kit is a viable option for laboratories seeking CE-IVD certified CFTR analysis.
