Single Nucleotide Polymorphisms-SNPs

Single Nucleotide Polymorphisms-SNPs

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,...

Area of Science:

Parasitology
Genomics
Molecular Biology

Background:

Clonorchis sinensis causes clonorchiasis, a disease affecting millions, and is linked to cholangiocarcinoma.
Current praziquantel treatment risks anthelmintic resistance, necessitating new intervention discovery.
Previous C. sinensis genome assemblies were fragmented, hindering molecular research.

Purpose of the Study:

To generate a high-quality, chromosome-level reference genome for C. sinensis.
To provide a valuable resource for molecular investigations into C. sinensis, clonorchiasis, and cholangiocarcinoma.
To facilitate the discovery of novel drug or vaccine targets for this neglected disease complex.

Main Methods:

Integrated use of second- and third-generation DNA sequencing technologies.
Advanced bioinformatic approaches to assemble and curate the genome.
Development of chromosome-level contiguity and refined gene models.

Main Results:

A substantially enhanced, high-quality reference genome for C. sinensis was successfully constructed.
The new genome assembly exhibits chromosome-level contiguity.
Curated gene models were established, improving genomic resource quality.

Conclusions:

The enhanced C. sinensis genome is a critical resource for advancing research.
This genomic advancement will accelerate the identification of new therapeutic and vaccine targets.
It supports the development of urgently needed interventions against clonorchiasis and associated cancers.
