What is Pfeiffer syndrome type 2?

Pfeiffer syndrome type II is characterized by a more severe form of craniosynostosis (Cloverleaf skull), with more severe hand and foot anomalies and additional malformations of the limbs.

What causes cloverleaf deformity?

Cloverleaf deformity is a genetic disorder that children inherit from parents. Mutated genes cause sutures to fuse together prematurely (craniosynostosis). The coronal (from ear to ear) and lambdoid (across the back of the head) sutures are most commonly involved.

What is cloverleaf skull syndrome?

Cloverleaf skull syndrome. A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present.
