Description : Klippel-Feil syndrome (KFS) is a congenital anomaly characterized by a defect in the
formation or segmentation of the cervical vertebrae, resulting in a fused appearance.
The clinical triad consists of short neck, low posterior hairline, and limited neck
movement, although less than 50% of patients demonstrate all 3 clinical features (Tracy
et al., 2004). For a general description and a discussion of genetic heterogeneity
of Klippel-Feil syndrome, see KFS1 (118100).;
