Other signs and symptoms include progressive microcephaly (very small head); ataxia (lack of coordination); spasticity ; and/or skin, hair and mild facial anomalies. It is caused by changes (mutations) in the CTNNB1 gene and it is inherited in an autosomal dominant fashion. Treatment is based on the signs and symptoms present in each person."
