Williams Syndrome: Causes, Symptoms, Diagnosis, Treatment and Prevention

Williams syndrome, also known as Williams-Beuren syndrome, is a rare genetic neurodevelopmental disease that presents with a range of symptoms, including unusual physical traits, delayed development, cognitive impairments, and circulatory system abnormalities. Most individuals with Williams syndrome are underweight, and children with the condition may have stunted growth. Endocrine problems include early puberty, an underactive thyroid, and high blood and urine calcium levels can also be brought on by Williams syndrome.

Causes Of William Syndrome

A section of chromosome 7 is deleted, or missing, which results in Williams syndrome.

Our bodies contain 46 chromosomes total, which are split up into 23 pairs. We are born with one copy of each pair of chromosomes from our parents. Sections of our chromosomes that contain genetic information, are called genes. Our genes contain the information our body needs to form and function.

Many genes make up chromosome 7, which is partially lost in Williams syndrome. Your genes are your body's instruction manual; if you don't have every chromosome, then some pages explaining the proper operation of chromosome 7 are missing. This missing of the chromosomes is responsible for the symptoms of William syndrome.

Symptoms of Williams Syndrome

Williams syndrome is characterized by a range of symptoms. Each person experiences Williams syndrome differently.

Symptoms of Williams syndrome include:

• Loss of hearing and/or recurring infections in the ears.
• Teeth abnormalities include thin enamel and small or absent teeth.
• Elevated calcium levels in the blood.
• Diabetes with adult-onset, hypothyroidism, and early puberty are examples of endocrine problems.
• Nutrition problems throughout their early years.
• Scoliosis.
• Problems with sleeping.
• Erratic walking or running.
• Williams syndrome has a number of symptoms that might be mistaken for other disorders and lead to alternative diagnosis.

Delays in the development

Children with Williams syndrome may find it more challenging to reach developmental milestones or tasks they can do by a given age. Developmental milestones show how your child thinks, learns, communicates, plays, moves, and behaves. Williams syndrome can cause the following milestones to be delayed:

• Learning (easy to moderately difficult cognitive activities).
• Speaking their initial speech.
• Sitting and moving with a body tone that is hypotrophic.
• Socialization (being outgoing and extroverted, finding it difficult to identify people, finding it difficult to concentrate, exhibiting excessive empathy, and experiencing phobias or worries).

Severe signs of Williams syndrome

One of the more serious indications and symptoms of Williams syndrome is cardiovascular illness. Stenosis, or the constriction of several blood vessels close to the heart, is common during foetal development. Elevated blood pressure, an irregular pulse, and finally cardiac failure can be caused by this constriction. Cardiac involvement is often one of the first signs that your child has Williams syndrome.

Physical characteristics associated to Williams syndrome

Certain physical characteristics that your child possesses from birth are indicative of Williams syndrome, and these include:

• Full Cheeks.
• Large ears.
• Smacking the lips.
• Small in size.
• Elevated nose.
• The inner corner of the eyes is covered in vertical skin folds called epiphanthal folds.
• Open mouth.

Diagnosis Of  Williams Syndrome 

Typically, the disease is identified when your child is still a newborn or young. If your child's doctor thinks they may have Williams syndrome, they will first examine them physically and, if necessary, order a genetic test, which is a blood test that looks for changes in certain genes.

Your healthcare provider may often ask for more testing to confirm the diagnosis and evaluate the symptoms of the disorder. Among the tests are:

• An electrocardiogram, or EKG, is a kind of cardiac ultrasonography that is used to check the heart for anomalies.
• Examine your child's blood pressure reading for any anomalies.
• Get a sample of your child's kidneys to determine whether they have kidney disease.

How Is Williams Syndrome Treated?

If a positive genetic test result and/or physical examination findings support the diagnosis of Williams syndrome, your healthcare provider will work with the appropriate specialists, such as a genetic counselor, to assist in explaining the condition to the afflicted person and their family.

Although there isn't a known treatment for Williams syndrome, it's important to recognize and handle any possible side effects. Each person's unique needs must be taken into account when designing interventions and therapies, which should include:

• Obtaining a professional evaluation from a physician. Your child's cardiologist will determine the best course of action if a heart problem is found in them.
• Seeking treatment for learning difficulties and/or developmental delays through therapy, special education, or early intervention initiatives.
• Seeking treatment for elevated blood calcium levels from a dietician or nephrologist.
• If you experience any new symptoms, see a specialist.

Prevention Of William Syndrome

Since Williams syndrome is a genetic disorder resulting from a chromosome change rather than something inherited from a parent, there is typically no way to prevent it. If you plan to become pregnant and would like to know the possible risks of having a child with a genetic condition, speak with your healthcare provider about genetic testing.
