| A rare genetic syndrome with characteristics of developmental delay and mild to moderate intellectual disability. Verbal language acquisition is usually delayed, with restricted language. The congenital heart defects are present in 41% of individuals, the most frequent being interatrial communication and interventricular communication. The syndrome is caused by heterozygous, usually de novo pathogenic or likely pathogenic variants in the CDK13 gene (7p14.1), coding for a protein which regulates transcription. Transmission is autosomal dominant however, in most situations, the pathogenic variants arise de novo, and thus, the risk of sibling recurrence is low. |

| Deletion 5q35 refers to the different congenital malformation syndromes resulting from deletions of variable extent of the terminal part of the long arm of chromosome 5 (5q), spanning the region from 5q35.1 to 5q35.3. The most significant anomaly is a recurring deletion in 5q35.2 comprising the NSD1 gene that causes Sotos syndrome that is characterized by cardinal features including excessive growth during childhood, macrocephaly, distinctive facial gestalt and various degrees of learning difficulty. Subtelomeric deletions of the terminal 3.5 Mb region on 5q35.3 are very rare, characterized by prenatal lymphedema with increased nuchal translucency, pronounced muscular hypotonia in infancy, borderline intelligence, postnatal short stature due to growth hormone deficiency, and a variety of minor anomalies such as mildly bell-shaped chest, minor congenital heart defects and a distinct facial gestalt. Larger deletions including bands 5q35.1, 5q35.2 and 5q35.3 cause a more severe phenotype that associates severe developmental delay with microcephaly, and significant cardiac defects (e.g. atrial septal defect with/without atrioventricular conduction defects, Ebstein anomaly, tetralogy of Fallot) linked to haploinsufficiency of NKX2.5 (5q35.1). Various combinations of signs may result from deletions of variable extent depending on the genes comprised in the deleted segment. |

| A rare primary bone dysplasia characterized by costovertebral ossification defects with small chest, abnormal vertebral segmentation, and posterior rib gaps containing incompletely differentiated mesenchymal tissue. Consistent dysmorphic craniofacial features include ocular hypertelorism, epicanthal folds, depressed nasal bridge with short nose, and low-set ears. The most common extraosseous manifestations are renal abnormalities such as multicystic kidneys. The disease is usually perinatally lethal due to respiratory insufficiency. |

| A rare, congenital, isolated hyperinsulinism disorder characterized by diazoxide unresponsive recurrent episodes of hyperinsulinemic hypoglycemia resulting from an excessive insulin secretion by the pancreatic beta-cells due to Kir6.2 deficiency. Hypoglycemia may lead to variable clinical manifestation, ranging from asymptomatic hypoglycemia revealed by routine blood glucose monitoring to macrosomia at birth, mild to moderate hepatomegaly and life-threatening hypoglycemic coma or status epilepticus, further leading to poor neurological outcome. |

| A rare, congenital, isolated hyperinsulinism disorder characterized by diazoxide unresponsive recurrent episodes of hyperinsulinemic hypoglycemia resulting from an excessive insulin secretion by the pancreatic beta-cells due to a mutation in the ABCC8 gene. Pancreatic involvement is focal and can be cured by a selective partial pancreatectomy. Hypoglycemia may lead to variable clinical manifestations, ranging from asymptomatic hypoglycemia revealed by routine blood glucose monitoring to macrosomia at birth, mild to moderate hepatomegaly and life-threatening hypoglycemic coma or status epilepticus, further leading to poor neurological outcome. |

| Diencephalic-mesencephalic junction dysplasia is a rare, genetic, non-syndromic cerebral malformation characterized by severe intellectual disability, progressive postnatal microcephaly, axial hypotonia, spastic quadriparesis, seizures and facial dysmorphism (bushy eyebrows, hairy forehead, broad nasal root, long flat philtrum, V-shaped upper lip). Additionally, talipes equinovarus, non-obstructive cardiomyopathy, persistent hyperplastic primary vitreous, obstructive hydrocephalus and autistic features may also be associated. On brain magnetic resonance imaging, the butterfly sign is characteristically observed and cortical calcifications, agenesis of the corpus callosum, ventriculomegaly, brainstem dysplasia and cerebellar vermis hypoplasia have also been described. |

Hypotonia or hypertonia with brisk reflexes, variable dysmorphic facial features, ophthalmological signs (cortical visual impairment, nystagmus, eye deviation) and episodes of sudden extreme agitation caused by severe illness may also be associated. |

| A rare pulmonary neuroendocrine tumor, most often presenting in women over 50 years and non-smokers, characterized by long-lasting cough (>10 years), and less frequently by dyspnea or wheezing. A proportion of patients are asymptomatic, the disease being an incidental finding during routine check-ups. Diffuse pulmonary nodules and mosaic attenuation can be detected by CT-scan however only histopathology can confirm the diagnosis detecting a multifocal hyperplasia of pulmonary neuroendocrine cells (carcinoid tumorlets). Ventilatory dysfunction can be obstructive and less often restrictive, mixed or non-specific. Symptoms can progress slowly but sometimes lead to respiratory failure. It is considered as a precursor for pulmonary carcinoid tumor. |

| Diffuse leptomeningeal melanocytosis is a rare tumor of meninges arising from leptomeningeal melanocytes, characterized by diffuse infiltration of the leptomeninges (pia mater and arachnoidea) anywhere in the central nervous system. Clinical features may include stillbirth, intracranial hypertension and hydrocephalus, seizure, ataxia, syringomyelia, cranial nerve palsy, intracranial hemorrhage, sphincter dysfunction and neuropsychiatric symptoms. Transformation into malignant melanoma of the central nervous system was reported. It may be associated with congenital nevi, as a part of neurocutaneous melanosis. |

Contrary to the clinical findings, histologic examination reveals findings suggestive of keratosis palmoplantaris striata, with orthohyperkeratosis featuring widening of the intercellular spaces and disadhesion of keratocytes in the upper epidermal layers. |

| Digestive duplication cyst of the tongue is an extremely rare otorhinolaryngological malformation which occurs during early embryogenesis and is characterized by a single, and on occasion multiple, cystic lesion that is most frequently located in the anterior portion of the tongue, either deeply embedded within it or superficially on it. Depending mostly on size and location of the cyst, patients could be asymptomatic or could present a wide array of symptoms, such as varying degrees of respiratory and feeding difficulties, lingual swelling and protrusion, dysphagia, and more rarely, recurrent bleeding or brownish discharge from a lingual sinus. |

Operation on the hands reveals extensor muscles and their tendons to be absent or hypoplastic. There have been no further descriptions in the literature since 1986. |

Additional signs and symptoms may include hypotonia, microcephaly, ocular abnormalities (such as microphthalmia, nystagmus, and strabismus), and autistic behavior, among others. Analysis of urine typically shows high levels of uracil and thymine. Patients are at risk of suffering from severe toxicity after the administration of the anti-neoplastic agent 5-fluorouracil. |

| Ketamine-induced biliary dilatation is an acquired biliary tract disease caused by the abusive consumption of ketamine, which results in the fusiform dilatation of the common bile ducts (CBD) without obstructive lesions or dilatation of the intrahepatic biliary ducts. Possible manifestations of the underlying cholangiopathy include epigastric pain and impaired liver function. Severity of CBD dilatation appears to correlate with the duration of ketamine consumption and the condition has been reported to be reversible in abstinent patients. |
