TERC/ABL levels are not reduced in patients with DC with TINF2 mutations. Comparison of TERC/ABL levels between healthy controls (n = 24), patients with DC with TINF2 mutations (n = 5), and patients with DC with DKC1 mutations (n = 26). The P value between TERC/ABL levels for TINF2 and DKC1 patients is given. The box represents the interquartile range which contains the 50% of values. The whiskers are lines that extend from the box to the highest and lowest values, excluding outliers (△). A line across the box indicates the median.
