We observed modest associations with 2 of 7 variants at the CDKN2A locus (variants previously associated with coronary heart disease) with parent's age at death (rs1333049 G allele beta=0.015, p=0.0015; rs4977574 A allele beta=0.014, p=0.0018); the CDKN2A variants associated with type-2 diabetes were not associated with parent's longevity. This evidence concerns the gene CDKN2A and type 2 diabetes mellitus.
