Micrognathia, and Cleft palate

Pierre-Robin syndrome (or Pierre-Robin sequence) is characterised by triad of orofacial morphological anomalies consisting of retrognathism, glossoptosis and a posterior median velopalatal cleft.

ISOLATED PIERRE ROBIN SYNDROME Is also known as isolated pierre robin sequence

• Micrognathia
• Cleft palate
• Neonatal respiratory distress
• Glossoptosis

Cleft palate as an isolated malformation behaves as an entity distinct from cleft lip with or without cleft palate (see {119530}).Dominantly inherited cleft soft palate in 4 generations has been reported (Jenkins and Stady, 1980); see {119570}.

CLEFT PALATE, ISOLATED; CPI Is also known as cp|cleft palate

• Seizures
• Micrognathia
• Cleft palate
• Cleft lip

Hydrolethalus syndrome is an autosomal recessive embryonic lethal disorder characterized by hydrocephaly or anencephaly, postaxial polydactyly of the upper limbs, and pre- or postaxial polydactyly of the lower limbs. Duplication of the hallux is a common finding. HLS2 is considered a ciliopathy (summary by Putoux et al., 2011).Acrocallosal syndrome (ACLS ) is an allelic disorder with a less severe phenotype.For a discussion of genetic heterogeneity of hydrolethalus syndrome, see {236680}.

Treacher Collins syndrome is a disorder of craniofacial development characterized by a combination of bilateral downward slanting of the palpebral fissures, colobomas of the lower eyelids with a paucity of eyelashes medial to the defect, hypoplasia of the facial bones, cleft palate, malformation of the external ears, atresia of the external auditory canals, and bilateral conductive hearing loss (Dauwerse et al., 2011).For additional phenotypic information and a discussion of genetic heterogeneity of Treacher Collins syndrome, see TCS1 (OMIM ).

Hamel cerebro-palato-cardiac syndrome is an X-linked intellectual disability syndrome (XLMR; see this term) characterized by intellectual deficiency, microcephaly and short stature. It belongs to the group of disorders collectively referred to as Renpenning syndrome (see this term).

Nemaline myopathy-9 is an autosomal recessive muscle disorder characterized by onset of muscle weakness in early infancy. The phenotype is highly variable, ranging from death in infancy due to lack of antigravity movements, to slowly progressive distal muscle weakness with preserved ambulation later in childhood. Muscle biopsy shows typical rod-like structure in myofibers (summary by Gupta et al., 2013).For a discussion of genetic heterogeneity of nemaline myopathy, see {161800}.

• Micrognathia
• Muscle weakness
• Cleft palate

Neu-Laxova syndrome-2 is a rare autosomal recessive disorder characterized by a recognizable pattern of severe congenital malformations leading to prenatal or early postnatal lethality. Affected patients have abnormal craniofacial features, microcephaly, intrauterine growth retardation, ichthyosis, flexion deformities, limb malformations, and edema of the hands and feet. Some patients have malformations of the central nervous system, such as abnormal gyration (summary by Acuna-Hidalgo et al., 2014).For a discussion of genetic heterogeneity of Neu-Laxova syndrome, see NLS1 (OMIM ).

• Scoliosis
• Growth delay
• Hypertelorism

Otospondylomegaepiphyseal dysplasia (OSMED) is characterized by sensorineural deafness and relatively short extremities with abnormally large knees and elbows but normal total body length. The diagnostic radiologic findings are the enlarged epiphyses combined with a moderate platyspondyly, most marked in the lower thoracic region. There are no ocular abnormalities. Patients have typical facial features, including midface hypoplasia (summary by Giedion et al., 1982). Some patients have osteoarthritis (Brunner et al., 1994).
