Diamund

Diamund directly compares DNA or exome sequences to identify candidate causative variants for genetic disease studies.

Key Features:

• Direct sequence comparison: Compares DNA sequences pairwise without aligning reads to the human reference genome.
• Reference-free filtering: Bypasses the human reference genome to reduce the number of candidate mutations reported.
• Candidate reduction: Significantly reduces the list of candidate variants to a more manageable size for downstream analysis.
• Sample applicability: Applicable to exome sequences from family trios and to comparisons of normal and diseased samples from the same individual.
• Sensitivity retention: Maintains sensitivity for detecting disease-causing variants while excluding many unrelated differences.
• Demonstrated performance: Applied to example cases, including analyses of two family trios, where it identified causative variants while excluding thousands of benign variants.

Scientific Applications:

• Family trio analysis: Identification and prioritization of causative variants from exome sequencing of family trios.
• Matched sample comparison: Detection and prioritization of variants by comparing normal and diseased samples from the same individual.
• Genetic disease research: Reduction and prioritization of candidate variants for follow-up studies in genetic disease investigations.

Methodology:

Direct comparison of DNA or exome sequences between samples without alignment to the human reference genome to filter and prioritize candidate variants.
