The adjusted mean telomere lengths in the white blood cells from two of the POT1 His226Asn variant carriers did not differ significantly from the values obtained from the blood donor control cohort (mean relative expression: 1.180 vs. 1.055, respectively, p = 0.645), nor when compared to other melanoma cases (mean relative expression: 1.180 vs 1.546, respectively, p = 0.492). The gene discussed is POT1; the disease is melanoma.
