Introduction to Mohr–Tranebjærg Syndrome
Mohr-Tranebjærg Syndrome (MTS) is a rare X-linked recessive disorder characterized by progressive sensorineural hearing impairment in early childhood, followed by neurodegeneration leading to a broader phenotypic spectrum․
Description and Background
Mohr-Tranebjærg Syndrome, also known as deafness-dystonia syndrome, is a rare X-linked recessive disorder characterized by sensorineural hearing loss in childhood, followed by progressive dystonia or ataxia in adolescence, visual impairment from early adulthood, and dementia in mid-life․ It is caused by mutations in the TIMM8A gene and typically presents with early childhood hearing impairment, leading to a progressive neurodegenerative course affecting various aspects of an individual’s health․
Clinical Manifestations of Mohr–Tranebjærg Syndrome
Mohr-Tranebjærg Syndrome, also known as deafness-dystonia syndrome, presents with early childhood sensorineural hearing loss progressing to dystonia or ataxia in adolescence, visual impairment in early adulthood, and dementia later in life․ It is characterized by a broad phenotypic spectrum affecting various aspects of an individual’s health․
Onset and Progression
Mohr-Tranebjærg Syndrome typically begins with sensorineural hearing loss in early childhood and progresses to manifestations such as progressive dystonia or ataxia in adolescence, visual impairment in early adulthood, and dementia later in life․ This neurodegenerative disorder has a variable presentation impacting various aspects of an individual’s health over time․
Mohr-Tranebjærg Syndrome is characterized by a wide range of symptoms, beginning with sensorineural hearing loss in childhood, followed by progressive dystonia or ataxia in adolescence, visual impairment in early adulthood, and dementia later in life․ This rare X-linked recessive disorder presents a complex clinical picture affecting various aspects of an individual’s health․
Genetic Basis of Mohr–Tranebjærg Syndrome
Mohr-Tranebjærg Syndrome is caused by a mutation in the TIMM8A gene, an X-linked recessive disorder leading to a range of symptoms starting with hearing loss in childhood and progressing to dystonia, visual impairment, and dementia later in life․
Characteristics and Symptoms
Mohr-Tranebjærg Syndrome, also known as deafness-dystonia syndrome, presents with a broad phenotypic spectrum․ It begins with sensorineural hearing loss in early childhood, progresses to dystonia or ataxia in adolescence, visual impairment in early adulthood, and dementia in mid-life․ This X-linked recessive disorder manifests with a range of symptoms affecting various aspects of an individual’s health over time․
Diagnosis and Prevalence of Mohr–Tranebjærg Syndrome
Clinical diagnosis often starts with the presentation of sensorineural hearing loss in childhood, followed by a series of progression of symptoms․ The prevalence of Mohr-Tranebjærg Syndrome is currently unknown, with more than 90 documented cases․
Diagnostic Approaches
Diagnosis of Mohr-Tranebjærg Syndrome often starts with clinical evaluation following the onset of sensorineural hearing loss in childhood․ Additional diagnostic tools may include genetic testing to identify mutations in the TIMM8A gene․ The complexity of symptoms and their progression over time require a multidisciplinary approach for accurate diagnosis and management of this rare X-linked recessive disorder․
Prevalence Data
Currently, the prevalence of Mohr-Tranebjærg Syndrome (MTS) is unknown․ However, there are over 90 documented cases involving 37 families, indicating the rarity of this X-linked recessive disorder․ The clinical description typically includes a rapidly progressive onset of sensorineural hearing loss in early childhood, which is a hallmark symptom of MTS․
