Abstract

Klippel-Feil Syndrome (KFS) is characterized by congenital vertebral fusion believed to result from faulty segmentation along the embryo's developing axis. KFS appears to be a heterogeneous disease often associated with craniofacial malformation. Here we provide the first evidence of a familial KFS gene locus on 8q, where an inv(8)(q22.2q23.3) has been found segregating with congenital vertebral fusion. The four-generation KF2-01 family present with dominant form of the KFS where the sequence of vertebral fusion was confined to the cervical spine (always including the C2-3 fusion and reduced expression of the C4-5 and C6-7 fusions) in association with malformation of laryngeal cartilages and mild-to-severe vocal impairment.
