AlleleAnalyzer

AlleleAnalyzer designs allele-specific single-guide RNAs (sgRNAs) for CRISPR/Cas-based genome editing to discriminate alleles differing by single nucleotide polymorphisms (SNPs) or short insertions and deletions (indels).

Key Features:

• Allele-Specific sgRNA Design: Creates sgRNAs tailored to specific genetic variants, including single nucleotide polymorphisms (SNPs) and short indels, enabling discrimination of alleles that differ by a single base pair.
• Support for Multiple Cas Proteins: Supports 11 different Cas proteins, enabling selection of enzymes based on target site constraints and desired efficiency.
• Population-Specific Optimization: Leverages patterns of shared genetic variation to optimize sgRNA design for diverse human populations.
• Variant-Aware Off-Target Minimization: Incorporates individual and population variants into design to reduce potential off-target effects.

Scientific Applications:

• Personalized Medicine: Enables precise allele-targeted editing to develop individualized therapeutic strategies.
• Genetic Research: Facilitates allele-specific interrogation of gene function and regulation.
• Population Genetics: Supports studies of human genetic diversity and evolution by optimizing sgRNAs across population variation.

Methodology:

Integrates comprehensive genomic variation data (single nucleotide variants and indels) into algorithmic sgRNA design, considers these variations to ensure allele specificity and minimize off-target effects, and incorporates population-specific genetic variation patterns.
