Summaries for Trichothiodystrophy 5, Nonphotosensitive

UniProtKB/Swiss-Prot : 76 Trichothiodystrophy 5, non-photosensitive: A X-linked form of trichothiodystrophy, a disease characterized by sulfur-deficient brittle hair and multisystem variable abnormalities. The spectrum of clinical features varies from mild disease with only hair involvement to severe disease with cutaneous, neurologic and profound developmental defects. Ichthyosis, intellectual and developmental disabilities, decreased fertility, abnormal characteristics at birth, ocular abnormalities, short stature, and infections are common manifestations. There are both photosensitive and non-photosensitive forms of the disorder. TTD5 features include microcephaly, profound intellectual disability, sparse brittle hair, aged appearance, short stature, facial dysmorphism, seizures, an immunoglobulin deficiency, multiple endocrine abnormalities, cerebellar hypoplasia and partial absence of the corpus callosum, in the absence of cellular photosensitivity and ichthyosis.

MalaCards based summary : Trichothiodystrophy 5, Nonphotosensitive, is also known as ttd5. An important gene associated with Trichothiodystrophy 5, Nonphotosensitive is RNF113A (Ring Finger Protein 113A). Affiliated tissues include brain, testes and thyroid, and related phenotypes are mandibular prognathia and short stature
