The first reported case of JAUD1 was in 2018, when a team of researchers identified a novel mutation in the JAUD1 gene in a patient with intellectual disability and seizures. Since then, several other cases have been reported, and the disorder has been recognized as a distinct clinical entity. Despite its recent discovery, JAUD1 has already been the subject of significant research, with scientists working to uncover the underlying causes of the disorder and develop effective treatments.
Causes of JAUD1
JAUD1 is caused by mutations in the JAUD1 gene, which is located on chromosome 15. The gene provides instructions for making a protein that plays a critical role in brain development and function. Mutations in the JAUD1 gene can disrupt the normal functioning of this protein, leading to the development of JAUD1.
Genetic Mutations
The genetic mutations that cause JAUD1 can occur in several different ways, including:
- Point mutations: These are changes in a single nucleotide base in the JAUD1 gene.
- Deletions: These are the loss of one or more nucleotide bases in the JAUD1 gene.
- Duplications: These are the duplication of one or more nucleotide bases in the JAUD1 gene.
Inheritance Pattern
JAUD1 is inherited in an autosomal dominant pattern, which means that a single copy of the mutated gene is enough to cause the disorder. This means that if one parent has the mutated gene, each child has a 50% chance of inheriting the mutation.
