Recovery of RNA synthesis (RRS) following UV irradiation. Fibroblasts of individuals 1 (△) and 2 (○) show a moderately decreased level of RRS as compared with the normal control cell line (♦), similar to a MED12 mutated cell line (●). A MED13L mutated cell line (x) shows a more severely decreased RRS level, closer to the typical severely decreased level of RRS in a CSA defective cell line (■). Error bars represent standard errors of the mean.
