Introduction
Williams syndromeIt is a non-hereditary symptom. About 20,000 of the babies born alive have Williams syndrome, which is unpredictable before it occurs. It brings both physical and developmental problems, including excessive social personality, and physical problems: heart defects, kidney damage, and lack of coordination, and may be accompanied by muscle weakness. Different brain damage problems can be found in some cases.
Williams syndrome is caused by the loss of two pairs of genes on chromosome 7. Patients with Williams syndrome usually love music and are extremely friendly.
Children with infant hypercalcemia (IHC) typically exhibit the same behavioral and educational problems as children with Williams syndrome. Therefore, in the description of the disease, they are grouped together. Children with hypercalcemia in infants have high levels of calcium in their blood and are stunted in all aspects.

In young children and newborn babies, they can be seen from the following signs: They have Williams syndrome:
1 difficulty in sucking, leading to feeding difficulties
2 high calcium in the blood
3 sleepiness
4 physical growth retardation
5 strabismus
In addition, all people with Williams syndrome seem to have heart problems, mainly supravalvular aortic stenosis, which sometimes develops into more complex heart problems. Perhaps the most obvious sign is the common facial features of Williams Syndrome children (hereafter referred to as William Children), which are known as "elf features." They have a typical wide mouth and a large, slack lower lip with a tip that turns up, a slightly convex cheek and irregular teeth, and a large gap.
