Short answer · Medically reviewed summary · Last updated: 2023-07-13
Megalocornea Intellectual Disability Syndrome is a rare genetic disorder characterized by an enlarged cornea and intellectual disability. It is caused by mutations in the ADAMTS17 gene, which is involved in the development and maintenance of the eye and brain. The inheritance pattern of this syndrome is autosomal recessive, meaning that both parents must carry a copy of the mutated gene for their child to be affected.

Is Megalocornea Intellectual Disability Syndrome hereditary? The genetic component explained in plain language, reviewed against medical sources, with patient experiences.
Megalocornea Intellectual Disability Syndrome is a rare genetic disorder characterized by an enlarged cornea and intellectual disability. It is caused by mutations in the ADAMTS17 gene, which is involved in the development and maintenance of the eye and brain.
The inheritance pattern of this syndrome is autosomal recessive, meaning that both parents must carry a copy of the mutated gene for their child to be affected. When both parents are carriers, there is a 25% chance with each pregnancy that the child will inherit two copies of the mutated gene and develop the syndrome.
It is important to note that not all individuals who inherit the mutated gene will develop the syndrome. Some carriers may only have an enlarged cornea without intellectual disability, while others may have mild intellectual impairment without significant eye abnormalities.
Genetic counseling is recommended for families with a history of Megalocornea Intellectual Disability Syndrome or for individuals who have been diagnosed with the syndrome. A genetic counselor can provide information about the specific genetic mutation involved, the likelihood of passing it on to future generations, and available testing options.
Early diagnosis and intervention are crucial for individuals with this syndrome. Treatment may involve managing the symptoms associated with intellectual disability, providing vision correction, and addressing any other medical issues that may arise.
