Question: Is familial idiopathic basal ganglia calcification inherited ?
Answer: FIBGC is inherited in an autosomal dominant pattern. Autosomal dominant inheritance means one copy of an altered SLC20A2 or PDGFRB gene in each cell is sufficient to cause the disorder. This condition appears to follow an autosomal dominant pattern of inheritance when the genetic cause is not known. In most cases, an affected person has one parent with the condition.
