Final answer:

Epilepsy and tremors are symptoms that can result from various genetic disorders, with chromosomal deletions causing numerous abnormalities. While Cri-du-chat syndrome is linked to a deletion on chromosome 5p, it's not typically associated with epilepsy or tremors. Diseases like Huntington's or progressive epilepsy linked to amyloid beta-induced hyperexcitability are examples of neurodegenerative conditions that might present such symptoms.

Step-by-step explanation:

Health conditions such as epilepsy and tremors that are linked to a deletion on the maternal chromosome are often associated with specific genetic disorders. One example is Cri-du-chat syndrome, which results from a deletion on chromosome 5p and leads to nervous system abnormalities among other physical features. This condition is not typically associated with epilepsy and tremors, but there are other genetic conditions like Huntington's disease and certain types of progressive epilepsy that may be linked to chromosomal abnormalities and present symptoms such as tremors and seizures.

While specific deletions causing epilepsy and tremors are complex and can vary, neurodegenerative diseases such as Huntington's disease, characterized by genetic mutations, can cause nervous system issues that deteriorate over time. Additionally, Amyloid beta-induced neuronal hyperexcitability has been linked to progressive epilepsy, as outlined in a study by Minkeviciene et al. (2009).

Fetal alcohol spectrum disorder, resulting from alcohol exposure during pregnancy, can lead to developmental delays and cognitive deficits, although it is not directly linked to chromosomal deletions. Similarly, rubella virus infection during pregnancy can result in a variety of birth defects, including cognitive deficits.
