Many individuals with Williams syndrome remain undiagnosed or are diagnosed at a relatively late age.

This is of concern since individuals with Williams syndrome can have significant and possibly progressive medical problems..

Chromosome 7, Partial Monosomy 7p is a rare chromosomal disorder characterized by deletion (monosomy) of a portion of the short arm (p) of chromosome 7 (7p). Associated symptoms and findings may be variable and may depend on the specific size and location of the deleted segment of 7p.

Who gets Moebius Syndrome?

Affected Populations Moebius syndrome affects males and females in equal numbers. The disorder is present at birth (congenital). The exact incidence and prevalence rates of Moebius syndrome are unknown. One estimate places the incidence at 1 case per 50,000 live births in the United States.

What chromosome is missing in autism?

A new study by a US research consortium has discovered that a small segment of chromosome 16 is either missing or duplicated in about 1 per cent of people with an autism spectrum disorder (ASD).

What does the 7th chromosome do?

Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. 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.

What is the lifespan of someone with Moebius syndrome?

With continued proper medical care, individuals with Moebius syndrome , who do not have serious life threatening complications in their first year of life, usually have a normal life expectancy.

Is there a disease where you can’t smile?

Moebius Syndrome is a rare disorder characterized by lifetime facial paralysis. People with Moebius Syndrome can’t smile or frown, and they often can’t blink or move their eyes from side to side. In some instances, the syndrome is also associated with physical problems in other parts of the body.

Is Moebius syndrome a disability?

Moebius syndrome might also be associated with a slightly increased risk of intellectual disability; however, the majority of those affected experience average intelligence. Researchers estimate the syndrome affects 1 in 50,000 to 1 in 500,000 newborns. A Child with Moebius syndrome May Also Experience: Teeth problems.

At what age is Williams Syndrome diagnosed?

Williams syndrome is usually diagnosed before a child is 4 years old. Your doctor will do an exam and ask about your family medical history. Then the doctor will look for facial features like an upturned nose, wide forehead, and small teeth. An electrocardiogram (EKG) or ultrasound can check for heart problems.

Is Williams syndrome a form of autism?

Autism spectrum disorders (ASD) and Williams syndrome (WS) both are neurodevelopmental disorders, each with a unique social phenotypic pattern.

What is an elfin face?

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.

What genes are in chromosome 7?

Chromosome 7 is the largest human chromosome to be sequenced so far. The analysis revealed that the chromosome has about 1,150 genes and 940 so-called pseudogenes, stretches of DNA that closely resemble genes but contain some genetic change that prevents them from functioning like a gene.

What causes trisomy 7?

The most likely mechanism of mUPD(7) in the present case is a trisomic zygote rescue. Given the maternal complete heterodisomy of chromosome 7 observed with molecular studies, it can be assumed that a trisomic zygote originated by maternal nondisjunction at the first meiotic cell division.

Does Williams syndrome make you happy?

And they found that people with Williams syndrome have a lot more oxytocin than everybody else, and that it fluctuates wildly in the brain. As a result, they feel this biological impulse to love all the time. (Read how oxytocin may help people with autism.)
