Potential relevance to the human ageing process

Main reason for selection
Entry selected based on evidence linking the gene product to a pathway or mechanism linked to ageing
Description

BLM is a helicase involved in DNA repair and replication. Mutations in BLM give rise to Bloom’s syndrome. Bloom’s syndrome cells are characterised by chromosomal aberrations including chromatid gaps and breaks, telomere association and quadriradial chromosomes, resulting from defects in DNA repair [4492]. Although Bloom’s syndrome is not considered accelerated ageing, BLM and WRN belong to the same family of proteins. Therefore, it is possible, even if unproven, that BLM plays a role in human ageing [444].
