Conditions with this feature

Crouzon syndrome
MedGen UID:
1162
Concept ID:
C0010273
Disease or Syndrome
Crouzon syndrome is an autosomal dominant disorder characterized by craniosynostosis causing secondary alterations of the facial bones and facial structure. Common features include hypertelorism, exophthalmos and external strabismus, parrot-beaked nose, short upper lip, hypoplastic maxilla, and a relative mandibular prognathism (Reardon et al., 1994; Glaser et al., 2000).
Oculoauriculovertebral spectrum with radial defects
MedGen UID:
67392
Concept ID:
C0220681
Disease or Syndrome
A rare branchial arches and limb primordia development disorder with characteristics of variable degrees of uni or bilateral craniofacial malformation and radial defects that result in extremely variable phenotypic manifestations. Characteristic features include low postnatal weight, short stature, vertebral defects, hearing loss, and facial dysmorphism (including facial asymmetry, external, middle and inner ear malformations, orofacial clefts, and mandibular hypoplasia). These features are invariably associated with radial defects, such as preaxial polydactyly, thumb and/or radius hypoplasia/agenesis, or triphalangeal thumb. Cardiac, pulmonary, renal, and central nervous system involvement has also been reported.
Hypertelorism, microtia, facial clefting syndrome
MedGen UID:
113104
Concept ID:
C0220742
Disease or Syndrome
A very rare syndrome with characteristics of the combination of hypertelorism, cleft lip and palate and microtia. Nine cases have been reported in the literature in seven families. Some patients have associated cardiac or renal congenital malformations. Short stature and intellectual deficiency are common. The reported cases support autosomal recessive inheritance.
Treacher Collins syndrome
MedGen UID:
66078
Concept ID:
C0242387
Disease or Syndrome
Treacher Collins syndrome (TCS) is characterized by bilateral and symmetric downslanting palpebral fissures, malar hypoplasia, micrognathia, and external ear abnormalities. Hypoplasia of the zygomatic bones and mandible can cause significant feeding and respiratory difficulties. About 40%-50% of individuals have conductive hearing loss attributed most commonly to malformation of the ossicles and hypoplasia of the middle ear cavities. Inner ear structures tend to be normal. Other, less common abnormalities include cleft palate and unilateral or bilateral choanal stenosis or atresia. Typically intellect is normal.
Pallister-Hall syndrome
MedGen UID:
120514
Concept ID:
C0265220
Disease or Syndrome
GLI3-related Pallister-Hall syndrome (GLI3-PHS) is characterized by a spectrum of anomalies ranging from polydactyly, asymptomatic bifid epiglottis, and hypothalamic hamartoma at the mild end to laryngotracheal cleft with neonatal lethality at the severe end. Individuals with mild GLI3-PHS may be incorrectly diagnosed as having isolated postaxial polydactyly type A. Individuals with GLI3-PHS can have pituitary insufficiency and may die as neonates from undiagnosed and untreated adrenal insufficiency.
Craniofacial microsomia
MedGen UID:
75554
Concept ID:
C0265240
Disease or Syndrome
A rare congenital malformation syndrome, most commonly presenting with hemifacial microsomia associated with ear and/or eye malformations and vertebral anomalies of variable severity. Additional malformations involving the heart, kidneys, central nervous, digestive and skeletal systems may also be associated. The phenotypic spectrum ranges from isolated mild facial asymmetry to severe bilateral craniofacial microsomia and additional multiple extracranial abnormalities. Intelligence is typically normal. The aetiology is poorly understood but is suspected to be heterogeneous and multifactorial. The gene MYT1 (20q13.33) has been implicated in a few rare cases, and chromosomal abnormalities have been associated with some of the congenital malformations associated with this condition. The condition usually occurs sporadically, but autosomal dominant inheritance has been reported.
Nager syndrome
MedGen UID:
120519
Concept ID:
C0265245
Disease or Syndrome
Nager syndrome is the prototype for a group of disorders collectively referred to as the acrofacial dysostoses (AFDs), which are characterized by malformation of the craniofacial skeleton and the limbs. The major facial features of Nager syndrome 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 hypoplasia or aplasia, and radioulnar synostosis. Phocomelia of the upper limbs and, occasionally, lower-limb defects have also been reported. The presence of anterior upper-limb defects and the typical lack of lower-limb involvement distinguishes Nager syndrome from Miller syndrome (263750), another rare AFD; however, distinguishing Nager syndrome from other AFDs, including Miller syndrome, can be challenging (summary by Bernier et al., 2012).

Disease or Syndrome
Aural atresia, congenital
MedGen UID:
375051
Concept ID:
C1842937
Disease or Syndrome
Altmann (1955) was the first to describe a congenital aural atresia (CAA) classification, which has been modified over the years (Cremers et al., 1988; Schuknecht, 1989; Jahrsdoerfer et al., 1992). In CAA type I, there is bony or fibrous atresia of the lateral part of the external auditory canal and an almost normal medial part and middle ear. CAA type II is the most frequent type and is characterized by partial or total aplasia of the external auditory canal. CAA type IIA involves an external auditory canal with either complete bony atresia of the medial part or partial aplasia that ends blindly in a fistula leading to a rudimentary tympanic membrane. CAA type IIB is characterized by bony stenosis of the total length of the external auditory canal. CAA type III involves bony atresia of the external auditory canal and a very small or absent middle-ear cavity (summary by Feenstra et al., 2011).

Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A1
MedGen UID:
924974
Concept ID:
C4284790
Disease or Syndrome
Congenital muscular dystrophy-dystroglycanopathy with brain and eye anomalies (type A), which includes both the more severe Walker-Warburg syndrome (WWS) and the slightly less severe muscle-eye-brain disease (MEB), is a genetically heterogeneous autosomal recessive disorder with characteristic brain and eye malformations, profound mental retardation, congenital muscular dystrophy, and early death. The phenotype commonly includes cobblestone (type II) lissencephaly, cerebellar malformations, and retinal malformations. More variable features include macrocephaly or microcephaly, hypoplasia of midline brain structures, ventricular dilatation, microphthalmia, cleft lip/palate, and congenital contractures (Dobyns et al., 1989). Those with a more severe phenotype characterized as Walker-Warburg syndrome often die within the first year of life, whereas those characterized as having muscle-eye-brain disease may rarely acquire the ability to walk and to speak a few words. These are part of a group of disorders resulting from defective glycosylation of DAG1 (128239), collectively known as 'dystroglycanopathies' (Godfrey et al., 2007). Genetic Heterogeneity of Congenital Muscular Dystrophy-Dystroglycanopathy with Brain and Eye Anomalies (Type A) Muscular dystrophy-dystroglycanopathy with brain and eye anomalies (type A) is genetically heterogeneous and can be caused by mutation in other genes involved in DAG1 glycosylation: see MDDGA2 (613150), caused by mutation in the POMT2 gene (607439); MDDGA3 (253280), caused by mutation in the POMGNT1 gene (606822); MDDGA4 (253800), caused by mutation in the FKTN gene (607440); MDDGA5 (613153), caused by mutation in the FKRP gene (606596); MDDGA6 (613154), caused by mutation in the LARGE gene (603590); MDDGA7 (614643), caused by mutation in the ISPD gene (CRPPA; 614631); MDDGA8 (614830) caused by mutation in the GTDC2 gene (POMGNT2; 614828); MDDGA9 (616538), caused by mutation in the DAG1 gene (128239); MDDGA10 (615041), caused by mutation in the TMEM5 gene (RXYLT1; 605862); MDDGA11 (615181), caused by mutation in the B3GALNT2 gene (610194); MDDGA12 (615249), caused by mutation in the SGK196 gene (POMK; 615247); MDDGA13 (615287), caused by mutation in the B3GNT1 gene (B4GAT1; 605517); and MDDGA14 (615350), caused by mutation in the GMPPB gene (615320).
