Inheritance patterns and prenatal diagnosis

Inheritance patterns
Most cases are sporadic mutations. Once, established inheritance is autosomal dominant. Weaver syndrome inheritance probably has some pattern of inheritance though this has not been fully determined.

Prenatal diagnosis
Macrocephaly, large hands, long arms and excessive growth are detectable using ultrasound scanning. Genetic counselling is available for affected families.
