How RNA Sequencing Can Help Improve Diagnosis of Rare Diseases?

 

RNA sequencing is a genomic approach for the identification and quantification analysis of RNA molecules with the ultimate aim of studying cellular responses from a biological sample. The advent of RNA sequencing had fueled several innovations in the medical sector, by facilitating other techniques (that utilize RNA sequencing) such as single nucleotide polymorphisms identification, RNA editing, transcriptional profiling and differential gene expression analysis.

RNA sequencing offers massive diagnostic utility in terms of rare diseases, which ranges from rare muscular disorders to mitochondrial diseases such as mitochondrial depletion syndrome, Leigh’s syndrome, and Kearns-Sayre syndrome, among others. RNA sequencing is an emerging technique to assess progression of different rare diseases. It aids medical professionals to understand various genes linked with specific rare diseases, thereby offering specific treatment for patients.

The rise in the discovery of genes associated with rare diseases coupled with the declining cost of genome sequencing is anticipated to enhance research in the rare disease segment. This is likely to support sequencing, particularly RNA sequencing, in the upcoming years.

Based on the market intelligence published by BIS Research, titled “Global RNA Sequencing Market - Analysis and Forecast, 2019-2028”, the market is expected grow at a significant CAGR of 14.21% during the forecast period, 2019-2028. This growth is driven by factors including increasing adoption of personalized medicine due to decreasing cost of sequencing and increasing utility in predictive biomarkers and therapeutic response research.

Further, amongst the various applications of the RNA sequencing, including drug discovery, translation medicine, diagnostics, and other, the drug discovery segment emerges as a prominent segment. The segment contributed approximately 44.50% share in 2018 and is expected to cover a significant share in the application segment in 2028. This segment is driven by the increase in use of RNA sequencing to modify drugs to suit the requirements of a specific patient owing to the incorporation of precision medicine.

In the RNA sequencing segment, there are several needs that are yet to be addressed by the stakeholders present in the market. These needs are related to shortage of skilled professionals in the field of bioinformatics and genomics. To fulfil this shortage of skilled professionals, regulations for quality analysis and interpretation of sequencing results are required to be established.

Personal Care Ingredients Market Size, Share & Trends Analysis Report 2019-2029

The introduction and proliferation of bio-based ingredients in several industries, such as food and beverage, pharmaceuticals, and cosmetics, has been transforming the manufacturing landscape since 2000. Growing consumer inclination toward the adoption of bio-based products due to rising health and environmental concerns is driving the demand for bio-based ingredients in the cosmetics and personal care products. Besides, awareness among consumers regarding the harmful effects of synthetic ingredients chemicals has grown rapidly over the past years. In addition, the availability of green raw materials has also urged large cosmetic firms to develop bio-based cosmetic products. However, limited availability of raw material, due to erratic weather conditions and stringent environmental regulations, can pose substantial hurdles in the production of bio-based ingredients. Thus, leading companies have been focusing on developing new and sustainable ways of producing the ingredi...
