PenCards: a global and community-contributed public archive of variant penetrance

Penetrance is a crucial indicator for accurately assessing disease risk and plays a vital role in disease research, gene therapy, and genetic counseling. However, with penetrance data dispersed across various sources, efficiently accessing and consolidating this information becomes a challenge. A comprehensive platform that integrates penetrance is urgently needed. Here, we present PenCards, a global, community-contributed public archive of variant penetrance, by first collecting penetrance data from all published literature and then using large international cohorts to specifically calculate the penetrance of autism-related variants. PenCards contains a total of 244,531 variants—including 239,244 single nucleotide variants, 4,994 insertions and deletions, and 293 copy number variants, covering approximately 300 phenotypes. We also provide a submission portal for the dynamic updating of penetrance. Additionally, to help users efficiently access genetic information, we comprehensively integrate over 150 variant- and gene-level resources. In summary, PenCards is a powerful platform designed to advance genetic research and diagnostics. PenCards is publicly available at https://genemed.tech/pencards/.
