Syndrome that is characterised by the association of conotruncal heart defects, myelomeningocoele and craniofacial dysmorphism similar to that seen in monosomy 22q11. Only five cases have been reported in the literature. The identification, by FISH, of 22q11.2 deletions in the majority of reported cases (including the original cases described by Kousseff) indicated that this syndrome is part of the variable clinical spectrum of monosomy 22q11. However, the absence of a 22q11.2 deletion in one patient suggests Kousseff syndrome to be a causally heterogeneous disorder.
