WebTrichothiodystrophy (TTD) is a term introduced by Vera Price and coworkers in 1980 (Price et al. 1980) to describe a group of autosomal recessive neuroectodermal disorders whose defining feature is brittle hair with a cystein content less than half of normal.The designation derives from Greek: tricho, hair; thio, sulfur; dys, faulty; and trophe, nourishment. WebTrichothiodystrophy (TTD) is a rare autosomal recessive condition in which the hair is brittle, with trichoschisis and a low sulfur and cysteine content. On polarized microscopy, the hair displays an alternating dark and light banding pattern, which is referred to as tiger tail banding. TTD can be clinically divided into several types.
