Figure 6. Real-time PCR from lymphoblastoid cell lines from family MOL0931 and from controls. Relative PRPF31 expression in 13 controls, patients from family MOL0931 (931–1, 931–2, and 931–5), and individual 931–3 (unaffected carrier of the mutation) are shown. Error bars indicate standard deviations. The difference in gene expression between controls and patients is statistically significant (p = 1.3 × 10−4, by t test).
