Long-patch Base Excision Repair

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Comparing Copy Number Variations and SNPs

Comparing Copy Number Variations and SNPs

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Point and Frameshift Mutations

Point and Frameshift Mutations

Point mutations are genetic alterations involving the change of a single nucleotide base pair in DNA. Depending on how the alteration affects protein synthesis, they can lead to various consequences.Point mutations fall into the following types:Silent mutations occur when a nucleotide change does not alter the amino acid sequence due to the redundancy of the genetic code. For instance, changing ACC to ACA still encodes threonine, leaving the protein function unaffected. This occurs because...

Area of Science:

Genomics
Bioinformatics
Computational Biology

Background:

Read-depths (RDs) are crucial for identifying structural variants (SVs) in sequencing data.
Current RD-based SV callers struggle with single-nucleotide resolution breakpoints due to data noise and binning methods.

Purpose of the Study:

To develop a method for enhancing the breakpoint resolution of RD-based SV callers.
To leverage deep learning for improved accuracy in SV breakpoint identification.

Main Methods:

Utilized the UNet deep segmentation model to learn base-wise RD patterns around known SV breakpoints.
Integrated UNet predictions into an existing RD-based SV caller.
Developed the RDBKE (Read-Depth Breakpoint Knowledge Enhancement) pipeline.

Main Results:

Demonstrated UNet's ability to train effectively with limited data and generalize across samples.
The RDBKE pipeline significantly improved the number of SVs with single-nucleotide resolution breakpoints.
Validation on both simulated and real sequencing data confirmed the pipeline's efficacy.

Conclusions:

The RDBKE pipeline, powered by UNet, offers a substantial advancement in precise SV breakpoint detection.
This deep learning approach overcomes limitations of traditional RD-based methods for SV analysis.
RDBKE provides a valuable tool for more accurate genomic variant calling.
