Slowly progressing nucleotide excision repair in trichothiodystrophy group A patient fibroblasts.

Trichothiodystrophy (TTD) is a rare autosomal premature-ageing and neuroectodermal disease. The photohypersensitive form of TTD is caused by inherited mutations in three of the 10 subunits of the basal transcription factor TFIIH. TFIIH is an essential transcription initiation factor that is also pivotal for nucleotide excision repair (NER). Photosensitive… CONTINUE READING
