PM3-related evidence sparsity

PM3-related evidence was sparse relative to the full variant–publication search space. Among 102,309 canonical records, 2,862 (2.80%) were classified as PM3-related evidence, including 191 phase-confirmed records and 2,671 phase-unconfirmed biallelic evidence records. These records involved 2,072 index variants across 620 genes, indicating that PM3-relevant observations are distributed across a broad gene space but remain uncommon at the level of individual variant–publication pairs.

This sparsity highlights a central challenge for PM3-oriented interpretation: clinically relevant genotype evidence is scattered across a large literature corpus, while most candidate variant–publication associations do not provide usable PM3 evidence. A dedicated PM3 database is therefore valuable not because PM3 evidence is abundant, but because it is rare, fragmented, and difficult to identify efficiently through publication-level search alone.
