Solver output
him-6 encodes the C. elegans ortholog of the RecQ helicase BLM (Bloom syndrome helicase), which resolves Holliday junctions and other aberrant DNA structures via its 3'-5' and four-way junction helicase activities. BLM-family helicases are critical for suppressing illegitimate recombination, facilitating DNA double-strand break repair through homologous recombination, and preventing replication fork collapse. Loss of RecQ helicase function leads to elevated genomic instability, accumulation of DNA damage, and accelerated aging phenotypes in multiple organisms. By maintaining genome integrity and resolving toxic recombination intermediates, him-6/BLM activity directly opposes the genomic instability hallmark of aging, thereby promoting longevity.
GenAge curators classify each gene's normal function as promoting (Pro-Longevity) or opposing (Anti-Longevity) longevity, based on synthesis across studies. Loss-of-function effects can vary from this depending on the manipulation.
Advisor judgment
The model correctly predicted pro_longevity for him-6 with high confidence (0.82). The mechanistic reasoning is sound and well-articulated: him-6 encodes the C. elegans BLM ortholog (RecQ helicase), which maintains genome integrity by resolving Holliday junctions, preventing illegitimate recombination, and stabilizing replication forks. Loss of function leads to genomic instability and accelerated aging, making it pro-longevity when functional. The mechanism class (genomic_instability) and key pathways identified are all appropriate and accurate.
