Summaries for Klippel-Feil Syndrome 2, Autosomal Recessive

OMIM : 58 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). (214300)

MalaCards based summary : Klippel-Feil Syndrome 2, Autosomal Recessive, also known as kfs2, is related to klippel-feil syndrome and spinal disease. An important gene associated with Klippel-Feil Syndrome 2, Autosomal Recessive is MEOX1 (Mesenchyme Homeobox 1). Affiliated tissues include bone, and related phenotypes are short neck and scoliosis

UniProtKB/Swiss-Prot : 76 Klippel-Feil syndrome 2, autosomal recessive: A skeletal disorder characterized by congenital fusion of cervical vertebrae. It is due to a failure in the normal segmentation of vertebrae during the early weeks of fetal development. The clinical triad consists of short neck, low posterior hairline, and limited neck movement.
