Trichothiodystrophy or sulphur-deficient brittle hair is a clinical marker
for several autosomal recessive neurocutaneous syndromes. The typical hair
abnormality is frequently associated with many alterations affecting the sk
in. nervous system, eves and bones as well as the immune, gonadal and endoc
rine systems. We report the first cases of dilated cardiomyopathy in two si
sters with trichothiodystrophy, leading to cerebral infarction in the young
er one. In addition, both suffer from severe hearing impairment. osteoscler
osis, and psychomotor retardation with central hypomyelination. Conclusion:
severe cardiac involvement and stroke may be associated features of tricho
thiodystrophy.
