Hirschsprung disease-nail hypoplasia-dysmorphism syndrome is a fatal malformative disorder that is characterised by Hirschsprung disease, hypoplastic nails, distal limb hypoplasia and minor craniofacial dysmorphic features (flat facies, upward slanting palpebral fissures, narrow philtrum, narrow, high arched palate, micrognathia, low set ears with abnormal helices). Hydronephrosis has also been reported. There have been no further descriptions in the literature since 1988. |

A rare ectodermal dysplasia syndrome characterized by hypotrichosis of scalp and eyebrows, finger syndactyly, intellectual disability and early eruption of teeth. Facial dysmorphism (i.e. round face with prominent forehead, cheeks and ears, and upward-slanting palpebral fissures), hypoplasia of median and distal phalanges, and kyphosis are additionally observed features. There have been no further descriptions in the literature since 1996. |

Noneruption of teeth - maxillary hypoplasia - genu valgum is an extremely rare syndrome that is characterized by multiple unerupted permanent teeth, hypoplasia of the alveolar process and of the maxillo-zygomatic region, severe genu valgum and deformed ears. |

Severe intellectual disability-epilepsy-anal anomalies-distal phalangeal hypoplasia is characterized by severe intellectual deficit, epilepsy, hypoplasia of the terminal phalanges, and an anteriorly displaced anus. It has been described in two sisters born to consanguineous parents. The syndrome is transmitted as an autosomal recessive trait and appears to be caused by anomalies in two chromosome regions, one localized to chromosome 1 and the other to chromosome 14. |

Ichthyosis-hypotrichosis syndrome is characterized by congenital ichthyosis and hypotrichosis. It has been described in three members of a consanguineous Arab Israeli family. The syndrome is transmitted as an autosomal recessive trait and is caused by a missense mutation in the ST14 gene, encoding the recently identified protease, matriptase. Analysis of skin samples from the patients suggests that this enzyme plays a role in epidermal desquamation. |

Metaphyseal dysplasia-maxillary hypoplasia-brachydactyly syndrome is characterized by metaphyseal dysplasia associated with short stature and facial dysmorphism (a beaked nose, short philtrum, thin lips, maxillary hypoplasia, dystrophic yellowish teeth) and acral anomalies (short fifth metacarpals and/or short middle phalanges of fingers two and five). It has been described in several members spanning four generations of a French-Canadian family. The syndrome is likely to be transmitted as an autosomal dominant trait. |

Hereditary hypotrichosis with recurrent skin vesicles is a very rare inherited hair loss disorder described in a family and characterized by sparse, fragile or absent hair on the scalp, eyebrows, eyelashes, axillae and rest of the body, associated with vesicle formation on various parts of the scalp and body which regularly burst and release watery fluid. |

A rare branchial arches and limb primordia development disorder characterized by 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. |

Stimmler syndrome is characterized by the association of microcephaly, low birth weight and severe intellectual deficit with dwarfism, small teeth and diabetes mellitus. Two cases have been described. Biochemical tests reveal the presence of high levels of alanine in the urine and elevated alanine, pyruvate and lactate levels in the blood. |

Hypotrichosis-osteolysis-periodontitis-palmoplantar keratoderma syndrome is an extremely rare ectodermal dysplasia syndrome characterized by hypotrichosis universalis with mild to severe scarring alopecia, acro-osteolysis, onychogryphosis, thin and tapered fingertips, periodontitis and caries leading to premature teeth loss, linear or reticular palmoplantar keratoderma and erythematous, scaling, psoriasis-like skin lesions on arms and legs. Lingua plicata and ventricular tachycardia have also been observed. |
