Yes, Williams syndrome is a genetic condition caused by a deletion of genetic material on chromosome 7. This deletion is not usually inherited, but occurs randomly. It is not considered a mutation in the traditional sense, but rather a genetic anomaly.

A deletion mutation occurs when a nucleotide is dropped from a DNA sequence. This can cause a shift in the reading frame, leading to a non-functional protein being produced.
deletion syndrome is a disorder caused by the deletion of a small piece of chromosome 22. The deletion occurs near the middle of the chromosome at a location designated q11.2.
The mutation caused by the addition of a nucleotide to an existing gene sequence is called an "insertion." This type of mutation can disrupt the reading frame of the gene, potentially leading to significant changes in the resulting protein. If the insertion occurs within a coding region, it can alter the amino acid sequence and affect the protein's function.
A deletion mutation can be dominant or recessive, depending on the specific gene affected and the consequences of the deletion on the protein encoded by that gene. In general, the impact of a deletion mutation on an individual's phenotype will determine whether it is dominant or recessive.
Yes, Angelman syndrome is caused by a mutation in a gene called UBE3A. This gene is responsible for producing a protein that is vital for normal brain function. The mutation leads to the characteristic symptoms of Angelman syndrome.
Deletion occurs when a whole segment of a gene is lost.
