Deafness-Dystonia-Optic Neuropathy (DDON) Syndrome is a rare X-linked progressive neurodegenerative disorder resulting from mutations in the TIMM8A gene encoding for the deafness dystonia protein 1 (DDP1).

Mohr–Tranebjaerg syndrome (MTS) (also named deafness–dystonia syndrome) is a rare X‐linked recessive deafness syndrome associated with dystonia and other neurological abnormalities (Mohr and Mageroy, 1960; Tranebjaerg et al., 1995). Early‐onset

X‐linked dystonia‐deafness syndrome, Movement …

We report a family with early‐onset deafness and progressive dystonia exclusively involving males over two successive generations. There is also evidence of cognitive impairment and corticospinal tract involvement. The pedigree suggests an X‐linked inheritance. A similar family was originally described by Scribanu and Kennedy. Tranebjaerg et al. have recently reported two other families

 · MEGDEL syndrome is a rare disorder caused by bi-allelic mutations in SERAC1, which encodes a protein of the mitochondrial membrane. 1 Typically, the phenotype is one of major motor (dystonia and spasticity) and intellectual disability that starts early in life and is associated with deafness; most patients never learn to speak or walk. 2 3-Methylglutaconic aciduria is a cardinal …

In other cases, these disorders also have a deafness component, for example in the case of TIMM8A, which is associated with deafness-dystonia-optic neuropathy syndrome (Tranebjaerg, 1993). However, these syndromic disorders are very complex, and in some cases, different mutations in the same gene lead to isolated optic atrophy or ataxias, such as the case of AFG3L2 ( Di Bella et al., 2010

Deafness-Dystonia-Optic Neuropathy (DDON) Syndrome is a rare X-linked progressive neurodegenerative disorder resulting from mutations in the TIMM8A gene encoding for the deafness dystonia protein 1 (DDP1). Despite important progress in identifying and

Spectrum of movement disorders in mitochondrial diseases

Of interest is a well-defined syndrome characterized by deafness, dystonia, and optic neuropathy previously called Mohr-Tranebjaerg syndrome (MTS) due to mutations in TIMM8A. The gene is located on chromosome X and encodes for a protein (deafness dystonia protein 1) located in the inner mitochondrial membrane and implicated in the mitochondrial protein transport system [ 34 , 35 ] .

What is shorthand of Deafness-Dystonia-Optic Atrophy Syndrome? The most common shorthand of “Deafness-Dystonia-Optic Atrophy Syndrome” is DDP. You can also look at abbreviations and acronyms with word DDP in term.
