26463438 Low levels of GTF2H5 are associated with enhanced prognosis in high-grade serous ovarian cancer patients and may contribute to cisplatin sensitization.
25620205 Transcriptional differences found between various TFIIH subunit variants participate in the phenotypic variability observed among xeroderma pigmentosum, XP associated with Cockayne syndrome, and trichothiodystrophy individuals.
23729738 Findings give new insights into the behavior of TTDA within the context of a living cell and thereby shed light on the complex phenotype of TTD-A patients.

18270339 Observational study and meta-analysis of gene-disease association. (HuGE Navigator)
17350038 The solution structure of the p8/TTD-A protein, a small alpha/beta protein built around an antiparallel beta-sheet that forms a homodimer with an extended interface, is reported.
16669699 TTDA is the first Transcription Factor IIH subunit with a primarily nucleotide excision repair-dedicated role in vivo.
16427011 p8/TTD-A, the tenth subunit of TFIIH, has a critical role in DNA repair where it triggers DNA opening by stimulating XPB ATPase activity together with the damage recognition factor XPC-hHR23B.
