Polygenic modifiers impact penetrance and expressivity in telomere biology disorders
3 Jun 2025
Abstract excerpt
BACKGROUNDTelomere biology disorders (TBDs) exhibit incomplete penetrance and variable expressivity, even among individuals harboring the same pathogenic variant. We assessed whether common genetic variants associated with telomere length combine with large-effect variants to impact penetrance and expressivity in TBDs.METHODSWe constructed polygenic scores (PGS) for telomere length in the UK Biobank to quantify...
