About this section


OMIM:45 Trichothiodystrophy (TTD) is a term introduced by Price et al. (1980) for sulfur-deficient brittle hair. Patients with... (601675) more...

MalaCards based summary: Trichothiodystrophy, also known as photosensitive trichothiodystrophy, is related to xeroderma pigmentosum, group d and cockayne syndrome, and has symptoms including autosomal recessive inheritance, hypogonadism and microcephaly. An important gene associated with Trichothiodystrophy is GTF2H5 (general transcription factor IIH, polypeptide 5), and among its related pathways are Formation of RNA Pol II elongation complex and HIV Life Cycle. The compounds cpds and ecteinascidin 743 have been mentioned in the context of this disorder. Affiliated tissues include skin, brain and testes, and related mouse phenotypes are pigmentation and tumorigenesis.

Genetics Home Reference:21 Trichothiodystrophy, which is commonly called TTD, is a rare inherited condition that affects many parts of the body. The hallmark of this condition is brittle hair that is sparse and easily broken. Tests show that the hair is lacking sulfur, an element that normally gives hair its strength.

NIH Rare Diseases:41 Tay syndrome is a rare genetic disorder characterized by congenital ichthyosis (dry, fish-like scaly skin present at birth) and abnormal brittle hair (trichothiodystrophy). last updated: 7/30/2013
