Mismatch Repair01:20

Mismatch Repair

6.3K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...

Pleiotropy01:33

Pleiotropy

43.2K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Comparing Copy Number Variations and SNPs02:26

Comparing Copy Number Variations and SNPs

18.6K
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%...

Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

6.8K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Point and Frameshift Mutations01:30

Point and Frameshift Mutations

823
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...

Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

17.9K
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:

  • Genetics
  • Molecular Biology
  • Bioinformatics

Background:

  • Synonymous mutations do not alter amino acid sequences but can affect protein function.
  • These subtle genetic variants are implicated in disease initiation and progression.
  • Accurate prediction of pathogenic synonymous mutations is vital for clinical diagnosis and treatment.

Purpose of the Study:

  • To develop a novel method, DRP-PSM, for predicting pathogenic synonymous mutations.
  • To integrate DNA, RNA, and protein-level biological features for a comprehensive prediction framework.
  • To elucidate the contribution of different biological levels to synonymous mutation pathogenicity.

Main Methods:

  • Developed DRP-PSM, a prediction method incorporating DNA, RNA, and protein features.
  • Systematically integrated sequence and structural features from DNA, RNA, and protein levels.
  • Evaluated the predictive power of features from distinct biological levels.

Main Results:

  • DNA-level features provided the largest contribution to prediction accuracy, followed by RNA-level features.
  • Protein-level features offered marginal predictive utility.
  • DNA conservation and splicing effect were dominant biological features, outperforming sequence/structure descriptors.

Conclusions:

  • Synonymous mutations primarily cause pathogenicity through effects on splicing or transcriptional efficiency.
  • Translational or post-translational processes are less significant contributors.
  • Understanding these regulatory mechanisms offers potential therapeutic targets.
