Metaphyseal dysostosis-intellectual disability-conductive deafness syndrome is a rare genetic disorder characterized by dysplasia of the metaphyses, short-limb dwarfism, mild intellectual deficit, and conductive hearing loss.
Definition and Description
Metaphyseal dysostosis-intellectual disability-conductive deafness syndrome is a rare genetic disorder characterized by dysplasia of the metaphyses, short-limb dwarfism, mild intellectual deficit, and conductive hearing loss. The syndrome is associated with repeated episodes of otitis media in childhood and may present with variable manifestations such as hyperopia and strabismus. It has been reported in siblings born to consanguineous parents, highlighting its autosomal recessive inheritance pattern.
Characteristics of the Syndrome
Metaphyseal dysostosis-intellectual disability-conductive deafness syndrome is defined by dysplasia of the metaphyses, short-limb dwarfism, mild intellectual deficit, and conductive hearing loss.
Metaphyseal Dysplasia
Metaphyseal dysplasia is a key characteristic of the metaphyseal dysostosis-intellectual disability-conductive deafness syndrome, involving abnormalities in the structure of bone regions adjacent to growth plates.
Short-Limb Dwarfism
Short-limb dwarfism is a prominent feature of metaphyseal dysostosis-intellectual disability-conductive deafness syndrome, often more noticeable in the lower limbs, reflecting the unique skeletal manifestations of the condition.
Mild Intellectual Deficit
Individuals with metaphyseal dysostosis-intellectual disability-conductive deafness syndrome may present with mild intellectual deficit as part of the constellation of symptoms that characterize the condition. This cognitive impairment is generally non-progressive and falls within the range of borderline to mild intellectual disability.
Conductive Hearing Loss
Individuals with metaphyseal dysostosis-intellectual disability-conductive deafness syndrome commonly experience conductive hearing loss, which refers to a type of hearing impairment caused by issues in the outer or middle ear that obstruct sound transmission to the inner ear.
Genetic Aspects
Metaphyseal dysostosis-intellectual disability-conductive deafness syndrome is a very rare genetic disorder characterized by dysplasia of the metaphyses, short-limbed dwarfism, mild intellectual disabilities, and conductive hearing loss. It has been observed in siblings born to consanguineous parents, indicating an autosomal recessive inheritance pattern.
Autosomal Recessive Inheritance
Metaphyseal dysostosis-intellectual disability-conductive deafness syndrome follows an autosomal recessive inheritance pattern. This means that both copies of the gene must be mutated for an individual to be affected. The syndrome has been reported in siblings born to consanguineous parents, where the mutation is present in both parents’ genetic makeup.
Clinical Manifestations
The clinical manifestations of metaphyseal dysostosis-intellectual disability-conductive deafness syndrome may include repeated episodes of otitis media in childhood and manifestations such as hyperopia, strabismus, mild intellectual deficit, and conductive hearing loss.
Repeated Episodes of Otitis Media
One of the clinical manifestations of metaphyseal dysostosis-intellectual disability-conductive deafness syndrome includes recurrent instances of otitis media during childhood. This condition contributes to the spectrum of symptoms associated with this rare genetic disorder.
Hyperopia and Strabismus
In individuals with metaphyseal dysostosis-intellectual disability-conductive deafness syndrome, manifestations such as hyperopia (farsightedness) and strabismus (eye misalignment) may be observed. These ocular conditions can be part of the clinical presentation of this rare genetic disorder.
Reported Cases
The metaphyseal dysostosis-intellectual disability-conductive deafness syndrome has been reported in siblings born to consanguineous parents, showcasing its rare genetic nature and complex manifestations.
