Single Nucleotide Polymorphisms-SNPs

14.8K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

  • To examine the integration of telemedicine testing data into clinical and research infrastructures.

Main Methods:

  • A feasibility study involving 100 participants comparing telemedicine-guided self-sampling (TG) with conventional healthcare professional (HCP)-performed testing (CG).
  • Telemedicine group received self-sampling kits, instructions, and results via a mobile app.
  • Key outcomes included feasibility, user satisfaction, and cost-effectiveness, with data interoperability assessed.

Main Results:

  • 95% of telemedicine participants received kits, and 76% returned samples.
  • SARS-CoV-2 PCR test completion rates were 95% in TG vs. 88% in CG.
  • High user satisfaction reported for ease of use, interface, and usefulness in the TG.
  • Telemedicine approach showed potential for interoperable data transmission supporting national platforms.

Conclusions:

  • Telemedicine-based SARS-CoV-2 testing is feasible and can be integrated into hospital data systems.
