| A rare, congenital disorder of glycosylation caused by mutations in the COG2 gene and characterized by normal presentation at birth, followed by progressive deterioration with postnatal microcephaly, developmental delay, intellectual disability, seizures, spastic quadriplegia, liver dysfunction, hypocupremia and hypoceruloplasminemia in the first year of life. Diffuse cerebral atrophy and thin corpus callosum may be observed on brain MRI. |

| A rare congenital disorder of glycosylation characterized by neonatal onset of global developmental delay, hypotonia, failure to thrive, hematological/immunological abnormalities, recurrent infections, liver involvement (with hepatosplenomegaly, cholestasis, fibrosis, or cirrhosis), and enteropathy. Additional reported manifestations include dysmorphic craniofacial features (such as microcephaly, broad palpebral fissures, and retrognathia), hypohidrosis, hyperkeratosis, and cardiac and musculoskeletal anomalies. Brain imaging may show hypoplastic corpus callosum, cerebral and cerebellar atrophy, and enlarged ventricles. |

| COG7-CDG is a congenital disorder of glycosylation characterized by dysmorphism, skeletal dysplasia, hypotonia, hepatosplenomegaly, jaundice, cardiac insufficiency, recurrent infections and epilepsy. To date, it has been described in two infants, both of whom died within the first three months of life. The syndrome is caused by a mutation in the gene encoding COG-7 (chromosome 16), a subunit of the oligomeric Golgi complex. |

| A rare lymphoma characterized by the concurrent occurrence of two or more histologic types of lymphoma involving the same anatomic site. Composite lymphomas can be combinations of two non-Hodgkin lymphomas or of a non-Hodgkin and a Hodgkin lymphoma. In many cases, the tumors are clonally related. Clinical presentation and treatment are determined by the more aggressive component. |

| Conductive deafness-ptosis-skeletal anomalies syndrome is a rare, genetic ectodermal dysplasia syndrome characterized by conductive hearing loss due to atresia of the external auditory canal and the middle ear complicated by chronic infection, ptosis and skeletal anomalies (internal rotation of hips, dislocation of the radial heads and fifth finger clinodactyly). In addition, a thin, pinched nose, delayed hair growth and dysplastic teeth are associated. There have been no further descriptions in the literature since 1978. |

| A very rare, syndromic genetic deafness characterized by mild to moderate conductive hearing loss, dysmorphic pinnae and lip pits or dimples. The pinnae are usually small, cup-shaped, with helix folded forward, and hearing loss is associated with malformed ossicles and displacement of the external auditory canal. |

| Cone dystrophy with supernormal rod response (CDSRR) is an inherited retinopathy, with an onset in the first or second decade of life, characterized by poor visual acuity (due to central scotoma), photophobia, severe dyschromatopsia, and occasionally, nystagmus. Night blindness usually develops later in the course of the disease, but it can also be apparent from childhood. A hallmark of CDSRR is the decreased and delayed dark-adapted response to dim flashes in electroretinographic recordings, which contrasts with the supernormal b-wave response at the highest levels of stimulation. |

| A rare sporadic arthrogryposis syndrome with characteristics of multiple congenital contractures presenting in a very specific pattern. It is typically symmetric, involving all four limbs, with internally rotated shoulders, fully extended and fixed elbows, the wrists fixed in flexion, partially flexed fingers, hips fixed in flexion or extension, adducted or abducted and sometimes dislocated. The knees may be fixed in extension or flexion and the feet are usually in severe equinovarus position. The jaw and trunk are relatively spared. Normal limb muscle tissue is replaced by fatty, fibrous tissue. |

| Congenital temporomandibular joint ankylosis is a rare maxillofacial disorder characterized by significant reduction in mouth opening (i.e. from a few millimeters to a few centimeters) in the absence of acquired factors (e.g. trauma, infection) contributing to the ankylosis. It is associated with variable degrees of facial dysmorphism (i.e. lateral deviation of the mandible and chin, lower facial asymmetry, retrognathia, micrognathia, dental malocclusion) and patients typically present with feeding and breathing difficulties. Developmental delay, hypotonia, seizures, and additional dysmorphic features (e.g. pectus excavatum, low-set ears, hypoplastic alae nasi) have also been reported. |

| A rare otorhinolaryngeal malformation characterized by a soft, fluctuant mass, abscess or draining tract along the anterior border of the lower half of sternocleidomastoid muscle, occasionally leading to development of retropharyngeal abscess, acute suppurative thyroiditis, stridor, respiratory distress, odynophagia, and dysphagia. Anomaly occurs as a tract from the piriform sinus to the thyroid gland. A fourth branchial cleft fistula passes deep to the superior laryngeal nerve but superficial to the recurrent laryngeal nerve, which is the main difference in comparison to the third branchial cleft fistula. |

Second branchial cleft fistulae and sinuses present with skin opening with chronic discharge and recurrent infections, whereas second branchial cleft cysts present as a painless, nontender, stable in size or slowly enlarging lateral neck masses. Cysts occasionally acutely increase in size during upper respiratory tract infection, leading to respiratory compromise, torticollis, and dysphagia. |
