Can Williams Syndrome go undiagnosed?
Williams syndrome often goes undiagnosed. This means many people fail to get the support and treatment they need until later in life. Diagnostic tests include: chromosome microarray testing – a chromosome test that detects Williams syndrome and many other small chromosome changes.

Down syndrome is more common than Williams syndrome, occurring in 1 in 600-800 births. It usually results from an additional copy of chromosome 21, the most common of which is trisomy 21. Williams syndrome is a much less common neurodevelopmental disorder caused by a submicroscopic deletion on chromosome 7q11, 23.Is Williams syndrome hereditary?
Williams syndrome is considered an autosomal dominant condition because one copy of the altered chromosome 7 in each cell is sufficient to cause the disorder. In a small percentage of cases, people with Williams syndrome inherit the chromosomal deletion from a parent with the condition.Can Williams syndrome be prevented?
Can Williams syndrome be prevented? There is no known way to prevent Williams syndrome. People with a family history of the condition can choose to undergo genetic counseling before conceiving a child.What is the opposite of autism?
Williams SyndromeWhat does the 7th chromosome do?
Chromosome 7 spans about 159 million DNA building blocks (base pairs) and represents more than 5 percent of the total DNA in cells. Chromosome 7 likely contains 900 to 1,000 genes that provide instructions for making proteins. These proteins perform a variety of different roles in the body.Can you have mild Williams syndrome?

Elfin facies is a form of facies where the patient presents with facial characteristics bearing some similarities to those traditionally associated with elves. It is characterized by prominent forehead, widely spaced eyes, upturned nose, underdeveloped mandible, dental hypoplasia, and patulous lips.Why is chromosome 7 important?
Other important genes found on chromosome 7 include those that help control cell division and cell death, genes for taste and smell receptors and those involved in immune responses. The centromere on chromosome 7 divides the chromosome into a short arm and a long arm, both of which carry many genes.Are there any celebrities with Williams syndrome?

Harlequin ichthyosis is a severe genetic disorder that mainly affects the skin. The newborn infant is covered with plates of thick skin that crack and split apart. The thick plates can pull at and distort facial features and can restrict breathing and eating. Mutations in the ABCA12 gene cause harlequin ichthyosis.How do you get Down syndrome?
Down syndrome is usually caused by an error in cell division called “nondisjunction.” Nondisjunction results in an embryo with three copies of chromosome 21 instead of the usual two. Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separate.What are some types of syndromes?
