Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

15.2K
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,...

Leaky Scanning

5.2K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Signal Sequences and Sorting Receptors01:41

Signal Sequences and Sorting Receptors

5.4K
Signal sequences are short amino acid sequences that guide newly synthesized proteins to their proper location within the cell. Classical signal sequences are fifteen to sixty amino acids long and present at the N-terminus of a polypeptide chain. Each signal sequence has a conserved segment of basic residues towards their N terminus, a hydrophobic core, and a C-terminus rich in polar residues. The C-terminus also contains a signal cleavage site and features a -3 -1 sequence motif. The -3-1...

Area of Science:

  • Genomics
  • Computational Biology
  • Biochemistry

Background:

  • Genetic mutations are a primary cause of many inherited diseases.
  • Identifying disease-causing mutations is crucial for diagnosis and treatment.
  • Traditional methods for mutation analysis can be time-consuming and complex.

Purpose of the Study:

  • To develop and validate a novel machine-learning algorithm for predicting the functional impact of genetic mutations.
  • To leverage protein structure prediction to identify mutations that disrupt protein function and lead to disease.

Main Methods:

  • Utilized a machine-learning model trained on a large dataset of known disease-causing and benign mutations.
  • Integrated protein structure prediction tools to analyze the structural consequences of mutations.
  • Developed a scoring system to quantify the potential pathogenicity of mutations based on structural and evolutionary information.

Main Results:

  • The algorithm accurately identified known disease-causing mutations with high sensitivity and specificity.
  • Predicted structural changes correlated well with experimentally determined functional effects.
  • Identified several novel candidate disease-causing mutations for further investigation.

Conclusions:

  • Machine-learning combined with structure prediction offers a powerful approach to identify disease-causing mutations.
  • This method can accelerate the discovery of genetic variants underlying human diseases.
  • The developed algorithm has the potential to be a valuable tool in clinical genetics and research.
