Distribution of age, gender, <i>CDKN2A</i>, pigmentation phenotype, and sun exposure variables in 53 melanoma-prone families by telomere length, stratified by CMM status.

1P-values were obtained by comparing individuals in the telomere tertiles using a generalized estimating equation accounting for familial correlation in the variance and adjusting for age at blood draw, gender, and DNA source. Short: <0.53; Medium: 0.53–0.72; Long: >0.72.
