MalaCards based summary: Acrofacial Dysostosis 1, Nager Type, also known as nager syndrome, is related to acrofacial dysostosis, palagonia type and acrofacial dysostosis, and has symptoms including Array, Array and Array. An important gene associated with Acrofacial Dysostosis 1, Nager Type is SF3B4 (Splicing Factor 3b Subunit 4), and among its related pathways is mRNA Splicing - Minor Pathway. Affiliated tissues include bone, uterus and skin.

Disease Ontology:11 An acrofacial dysostosis characterized by 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, in children.

Genetics Home Reference:25 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.

NIH Rare Diseases:48 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

UniProtKB/Swiss-Prot:70 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.
