A rare malformation syndrome that is characterized by short stature, hypoplastic fifth digits with tiny dysplastic nails, facial dysmorphism with coarse features including a wide mouth and broad nose, and mild intellectual disability. It has been suggested that Coffin-Siris syndrome and BOD syndrome are perhaps allelic variants. |

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, genetic, primary immunodeficiency due to a defect in adaptive immunity characterized by the triad of congenital athymia (resulting in severe T-cell immunodeficiency), congenital alopecia totalis and nail dystrophy. Patients present neonatal or infantile-onset, severe, recurrent, life-threatening infections and low or absent circulating T cells. Additional features reported include erythroderma, lymphoadenopathy, diarrhea and failure to thrive. |

Nail and teeth abnormalities-marginal palmoplantar keratoderma-oral hyperpigmentation syndrome is a rare genetic ectodermal dysplasia syndrome characterized by short stature, nail dystrophy and/or nail loss, oral mucosa and/or tongue hyperpigmentation, dentition abnormalities (delayed teeth eruption, hypodontia, enamel hypoplasia), keratoderma on the margins of the palms and soles and focal hyperkeratosis on the dorsum of the hands and feet. Additionally, dysphagia with esophageal strictures, sensorineural deafness, bronchial asthma and severe iron-deficiency anemia have been observed. |

Deafness-onychodystrophy syndrome is a group of rare, genetic, developmental defect during embryogenesis disorders characterized by the association of sensorineural deafness and onychodystrophy (e.g. absent/hypoplastic finger and toenails), as well as brachydactyly and finger-like thumbs. Additional features present in one of the diseases comprising this group include osteodystrophy, intellectual disability, seizures, developmental delay, and distinctive facies. |
