3. Small Head Size
Microcephaly is a birth defect where a newborn’s head is much smaller than what is normal for other babies of the same age and sex. Normally, during pregnancy, the brain develops and the head grows along with it. However, if the brain does not develop properly, microcephaly can occur. Importantly, this can occur alone or in combination with other congenital defects.
About a third of children with Williams syndrome are born with microcephaly.1Lazier, J., MD. (2020, December 05). Williams Syndrome Clinical Presentation: History, Physical Examination.

However, others may not develop significant complications of microcephaly.
