5 citations
,
July 1996 in “Journal of Cutaneous Medicine and Surgery” This study explains that while trichothiodystrophy and xeroderma pigmentosum share genetic defects, TTD patients primarily exhibit issues in transcription initiation, not the increased skin cancer risk seen in XP.
11 citations
,
January 1989 This case report describes two patients with trichothiodystrophy who exhibited a different pattern of hair protein composition changes, suggesting a subgroup of TTD characterized by partial loss of high-sulfur proteins without significant alteration in their amino acid composition.

7 citations
,
March 2004 in “Journal of the American Academy of Dermatology” Tiger tail banding and hair abnormalities are reliable indicators for diagnosing trichothiodystrophy.

April 2012 in “Neuropediatrics” This article reviews the genetic and phenotypic characteristics of Trichothiodystrophy and discusses the associated DNA repair defects, but does not report new clinical findings.
2 citations
,
January 2018 in “International Journal of Trichology” This case report describes trichothiodystrophy in two sisters with only hair fragility, illustrating the condition's variable presentation and the importance of regular monitoring for potential associated impairments.
January 2013 in “International Journal of Trichology” This case report describes a young girl with trichothiodystrophy and suggests the need for early diagnosis and multidisciplinary interventions for her educational challenges.
17 citations
,
September 2009 in “British Journal of Dermatology” This study suggests that clinically apparent fragile hair in children is rarely linked to trichothiodystrophy, and the tiger-tail pattern is not wholly specific to this diagnosis.
53 citations
,
March 2006 in “Biopolymers” This study suggests that increased amounts of less stable disulfide conformers in hair shafts may be linked to the brittleness observed in trichothiodystrophy.
