About this section
OMIM:49 Nager syndrome is the prototype for a group of disorders collectively referred to as the acrofacial dysostoses (AFDs),... (154400) more...

MalaCards based summary: Acrofacial Dysostosis 1, Nager Type, also known as nager syndrome, is related to dysostosis and tetralogy of fallot, and has symptoms including micrognathia, hearing impairment and downslanted palpebral fissures. An important gene associated with Acrofacial Dysostosis 1, Nager Type is SF3B4 (Splicing Factor 3b, Subunit 4, 49kDa), and among its related pathways are mRNA Splicing - Major Pathway and Gene Expression. Affiliated tissues include bone, skin and uterus.

Disease Ontology:10 A syndrome that affects the development of the face, hands, and arms. affected children have underdeveloped cheek bones, very small lower jaw, cleft palate, defects in the middle ear, absent eyelashes, and a notch in the lower eyelids called a coloboma.

NIH Rare Diseases:45 Nager acrofacial dysostosis is a genetic disorder that affects the limbs and face. the signs and symptoms of nager acrofacial dysostosis vary among affected individuals, even among those in the same family. treatment is tailored to the individual based upon their specific needs. this condition is caused by mutations in the sf3b4 gene. while most cases are sporadic (occurring in families with no prior history of the disorder), autosomal dominant and autosomal recessive inheritance have been reported. last updated: 2/25/2014

Genetics Home Reference:23 Nager syndrome is a rare condition that mainly affects the development of the face, hands, and arms. The severity of this disorder varies among affected individuals.

UniProtKB/Swiss-Prot:67 Acrofacial dysostosis 1, Nager type: A form of acrofacial dysostosis, a group of disorders which are characterized by malformation of the craniofacial skeleton and the limbs. The major facial features of AFD1 include downslanted palpebral fissures, midface retrusion, and micrognathia, the latter of which often requires the placement of a tracheostomy in early childhood. Limb defects typically involve the anterior (radial) elements of the upper limbs and manifest as small or absent thumbs, triphalangeal thumbs, radial hyoplasia or aplasia, and radioulnar synostosis. Phocomelia of the upper limbs and, occasionally, lower-limb defects have also been reported.
