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). Clarke et al. (1998) proposed a classification system for KFS in which
an autosomal recessive form is characterized by the most rostral fusion at C1 and
the presence of severe associated anomalies, including short neck, cardiac defects,
and craniofacial anomalies. For a general description and a discussion of genetic
heterogeneity of Klippel-Feil syndrome, see KFS1 (118100).;
