| A rare closed dysraphism with stalk characterised by a dorsal midline dermal sinus tract lined by keratinising stratified squamous epithelium extending to the intrathecal space. Other components such as hair follicles and shafts, mesenchymal derivatives (blood vessels and fibrous tissue) and occasionally nerve fibres can be observed. Inflamed granulation tissue containing mixed neutrophils, plasma cells, lymphocytes, and histiocytes is consistently found in the tract. It can also be associated with an intradural dermoid cyst. This malformation is at risk to cause intrathecal infections (meningitis, empyema) that justify prophylactic surgery. |

| Constriction rings syndrome is a congenital limb malformation disorder with an extremely variable clinical presentation characterized by the presence of partial to complete, congenital, fibrous, circumferential, constriction bands/rings on any part of the body, although a particular predilection for the upper or lower extremities is seen. Phenotypes range from only a mild skin indentation to complete amputation of parts of the fetus (e.g. digits, distal limb). Compression from the rings may lead to edema, skeletal anomalies (e.g. fractures, foot deformities) and, infrequently, neural compromise. |

| A rare genetic syndromic neurodevelopmental disorder with characteristics of moderate to mostly severe intellectual disability, speech impairment with normal or mildly delayed motor development and early-onset seizures often accompanied by developmental regression. Autistic behaviour and stereotypic movements are common. The disorder is caused by bi-allelic intragenic deletions (rarely duplications) or truncating variants in the CNTNAP2 gene (7q35-q36.1). It encodes contactin-associated protein 2 (CASPR2), a transmembrane protein from the neurexin superfamily, which is involved in neural-glia interactions and clustering of potassium channels in myelinated axons. Inheritance is autosomal recessive. |

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. |

| A syndromic disorder with, as a major feature, the association between Dandy-Walker malformation and postaxial polydactyly. The Dandy-Walker malformation has a variable expression and is characterized by a posterior fossa cyst communicating with the fourth ventricle, the partial or complete absence of the cerebellar vermis, and facultative hydrocephalus. Postaxial polydactyly includes tetramelic postaxial polydactyly of hands and feet with possible enlargement of the fifth metacarpal and metatarsal bones, as well as bifid fifth metacarpals. |

| A rare renal disease characterized by thrombotic microangiopathy developing de novo in kidney transplant recipients with no evidence of occurrence of the disease prior to transplantation. Precipitating factors include antibody-mediated rejection, immunosuppressive medication, viral infections, and genetic abnormalities in the complement cascade, among others. The condition most commonly occurs within the first 3-6 months post-transplantation. Clinical presentation is highly variable and ranges from a limited form confined to the kidney with relatively good prognosis to a systemic variant consisting of the classic triad of thrombocytopenia, microangiopathic hemolytic anemia, and acute kidney injury. |

| 3-hydroxy-3-methylglutaryl-CoA synthase deficiency (HMG-CoA synthase deficiency) is a rare autosomal recessively inherited disorder of ketone body metabolism, reported in less than 20 patients to date, characterized clinically by episodes of decompensation (often associated with gastroenteritis or fasting) that present with vomiting, lethargy, hepatomegaly, non ketotic hypoglycemia and, in rare cases, coma. Patients are mostly asymptomatic between acute episodes. HMG-CoA synthase deficiency requires an early diagnosis in order to avoid hypoglycemic crises that can lead to permanent brain damage or death. |
