The DECIPHER database now supports analysis of sequence variants like single nucleotide variants (SNVs) and insertions/deletions (InDels), alongside copy-number variants. This expansion enhances the identification and interpretation of genetic variations in rare developmental disorders.
Area of Science:
- Genetics and Bioinformatics
- Rare Disease Research
- Clinical Genomics
Background:
- The DECIPHER database is a key resource for rare disease research, housing genetic variation and phenotype data.
- It previously focused on copy-number variants but has been expanded to include sequence variants.
- An international consortium supports DECIPHER, involving over 200 clinical centers and 1600 experts.
Purpose of the Study:
- To update the DECIPHER database with new functionalities for analyzing genetic variations.
- To enable the integration and analysis of both copy-number and sequence variants (SNVs, InDels).
- To enhance tools for identifying genotype-phenotype correlations in rare disorders.
Main Methods:
- Extended DECIPHER's capabilities to include upload, annotation, and analysis of single nucleotide variants (SNVs) and InDels.
- Developed a customizable, interactive genome browser for visualizing sequence and copy-number variations.
- Integrated various bioinformatics resources and introduced new deposition and analysis features.
Main Results:
- DECIPHER now accommodates a broader range of genetic variation types, including SNVs and InDels.
- New visualization tools allow combined interpretation of different variant types against population and pathogenic datasets.
- Enhanced interface facilitates data deposition and analysis for researchers and clinicians.
Conclusions:
- The expanded DECIPHER database provides a more comprehensive platform for rare disease genetic research.
- Improved tools facilitate the identification of pathogenic genetic variations and genotype-phenotype correlations.
- DECIPHER continues to be a vital, evolving resource for the clinical interpretation of rare genetic disorders.

Comparing Copy Number Variations and SNPs
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%...
