Is Nicolaides-Baraitser syndrome inherited ?
How is Nicolaides-Baraitser syndrome inherited? Nicolaides-Baraitser syndrome (NCBRS) is inherited in an autosomal dominant manner. This means that having a change (mutation) in only one of the two copies of the responsible gene in each cell is enough to cause features of the condition. All known cases of NCBRS have been sporadic. This means it is thought that the mutation occurred for the first time in each affected person (called a de novo mutation). There have not been reports of NCBRS being inherited from a parent, or recurring in any family (with the exception of one pair of identical twins).
