Disorders of nucleotide excision repair [DS:H00403]
Trichothiodystrophy (TTD) is a premature aging syndrome, with the hallmark feature of brittle hair and nails, ichthyosis, and progressive mental and physical retardation. Within photo-sensitive TTD, three TFIIH coding genes (ERCC2, ERCC3, and TTDA/GTF2H5) are implicated. Non-photosensitive trichothiodystrophy (TTDN) is characterized by short stature, intellectual impairment, sulfur-deficient brittle hair, and decreased male fertility but not cutaneous photosensitivity. Mutations in MPLKIP, RNF113A, and GTF2E2 have been reported.
