Background:

Macrocephaly is a clinical diagnosis where the measured head circumference is larger than 2 standard deviations above the average for individuals at a common age. Abnormal skull formations are also associated to abnormalities in brain development and intellectual disabilities. These conditions can be inherited in an autosomal dominant, recessive or X-linked manner.

Reasons for Referral:

  • Head circumference measures greater than two standard deviations from normal
  • Suspected genetic etiology of a brain malformation
  • Carrier testing
  • Positive family history
