RExPrimer

RExPrimer designs PCR primers using Primer3 and validates them against annotated human SNP, indel, pseudogene, and structural genomic variation databases to avoid mis-priming and ensure primer specificity including consideration of population-specific SNPs at critical regions such as the 3' end.

Key Features:

• Integrated Primer Design Algorithm: Uses Primer3 for optimized PCR primer design based on established primer-selection criteria.
• Comprehensive Database Integration: Incorporates annotated human SNP, indel, pseudogene, and structural genomic variation databases to identify variant-induced mismatches and potential off-targets.
• Population-Specific Customization: Tailors primer selection using population-specific SNP data and specifically evaluates variants at the 3' end of primers.
• Robust Validation Capabilities: Validates primer sequences against integrated genomic variation data to reduce the risk of PCR failure and mis-priming.

Scientific Applications:

• PCR Primer Design: Addresses sequence complexity and homology challenges to produce primers with high specificity across diverse genetic backgrounds.

Methodology:

Computational implementation uses Primer3 for primer design and is developed in Python with MySQLv5.0 for retrieval and integration of sequence and genomic variant databases.
