Gene Expression and Existence Bit Strings Across Tissues and Clades

Bit strings encode the presence or absence of selected genes across large evolutionary clades. The dataset, created by Xiao Liang and last updated in May 2026, includes tissue-specific expression details for genes expressed in five or fewer tissues. It is a small dataset of 9.5 KB stored in an XLS file.

Use Cases

• Identify genes lost in multiple major clades based on the existence bit strings.
• Analyze tissue-restricted expression patterns for genes with limited high-expression profiles.
• Perform comparative genomic studies on gene presence/absence across evolutionary lineages.

Strengths

• Data is licensed under CC-BY-4.0 for open reuse.
• Includes a specific criterion for gene selection: absence from at least two large clades.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 9.5 KB, indicating limited scope.
