Orofaciodigital syndrome 1 (OFD1), also called Papillon-Léage and Psaume syndrome, is an X-linked congenital disorder characterized by malformations of the face, oral cavity, and digits with polycystic kidney disease and variable involvement of the central nervous system.
Lathosterolosis is an inborn error of cholesterol biosynthesis caused by a deficiency of the enzyme 3-beta-hydroxysteroid-delta-5-desaturase. This leads to a flaw in the conversion of lathosterol to 7-dehydrocholesterol. Characteristics include facial dysmorphism, congenital malformations, failure to thrive, developmental delay, and liver illness. Brunetti-Pierri et al. originally described Lathosterolosis in 2002.
Nablus mask-like facial syndrome is a rare genetic condition. It is a microdeletion syndrome triggered by a deletion at chromosome 8 q22.1 that causes a mask-like facial appearance in those affected. This syndrome typically presents itself in infants, specifically newborns.
Zeichi-Ceide syndrome is a rare disease discovered in 2007. It is named after its discoverer, R.M. Zeichi-Ceide, who observed three siblings born of consanguineous parents with distinctive characteristics, including facial anomalies, large feet, mental deficiency, and occipital atretic cephalocele. The investigators suspected the symptoms were caused by autosomal recessive inheritance.
Microcephalic primordial dwarfism, Montreal type is a rare, multi-systemic genetic disorder that is characterized by cranio-facial dysmorphy, premature hair greying and balding, dry and wrinkled palms, skeletal abnormalities, cryptorchidism, premature dementia and intellectual disabilities of variable severity.
Thumb stiffness-brachydactyly-intellectual disability syndrome is a very rare genetic disorder which is characterized by thumb ankylosis due to symphalangism, brachydactyly type A, intellectual disabilities, mild facial dysmorphia and variable levels of obesity.
MacDermot–Winter syndrome is a very rare fatal genetic disorder which is characterized by pre-natal developmental delay, cranio-facial dysmorphisms, genitalia hypoplasia and congenital-onset seizures. Its prevalence is less than 1 in a million live births.
Al Gazali Sabrinathan Nair syndrome, also known as Al Gazali-Nair syndrome is a very rare multi-systemic genetic disorder which is characterized by developmental delay, facial dysmorphy, and skeletal and ocular abnormalities. This disorder was first described in two siblings that came from consanguineous parents. No new cases have been described since 1994.
Aortic arch anomaly - peculiar facies - intellectual disability is a rare, genetic, congenital developmental anomaly which is characterized by heart abnormalities, cranio-facial dysmorphia, and intellectual disabilities. No new cases have been reported since 1968.
Brachial amelia, cleft lip, and holoprosencephaly, or Yim–Ebbin syndrome, is a very rare multi-systemic genetic disorder which is characterized by brachial amelia cleft lip, and forebrain defects such as holoprosencephaly. Approximately five cases of this disorder have been described in medical literature.
Pierre Robin sequence-faciodigital anomaly syndrome, also known as Chitayat Meunier Hodgkinson syndrome, is a very rare genetic disorder which is characterized by the signs typical of Pierre Robin sequence along with facial dysmorphisms and digital anomalies. Intellect is not affected. It is thought to be inherited in an X-linked recessive manner.
CHAMP1-associated intellectual disability syndrome, also known as autosomal dominant intellectual disability type 40, is a rare genetic disorder characterized by intellectual disabilities, developmental delays, facial dysmorphisms, and other anomalies.
Collins–Pope syndrome, also known as Dislocation of the hip-dysmorphism syndrome, is a rare autosomal dominant genetic disorder which is characterized by bilateral congenital hip dislocation, flattened mid-face, hypertelorism, epicanthus, puffy eyes, broad nasal bridge, carp-shaped mouth, and joint hypermobility. Additional findings include congenital heart defects, congenital knee dislocation, congenital inguinal hernia, and vesicoureteric reflux. It has been described in 4 members of a 2-generation family in the United Kingdom.
Thoracic dysplasia-hydrocephalus syndrome is a rare autosomal recessive genetic disorder characterized by shortening of the ribs, narrowing of the chest, mild shortening of the limbs (rhizomelia), hydrocephalus, and variable developmental delays. It has been described in two siblings born to consanguineous Pakistani parents.
Conductive deafness-ptosis-skeletal anomalies syndrome, also known as Jackson Barr syndrome is a rare presumably autosomal recessive genetic disorder characterized by conductive hearing loss associated with external auditory canal-middle ear atresia which aggravates during ear infections, ptosis, and skeletal anomalies which consist of clinodactyly of the fifth fingers, radial head dislocation and internal rotation of the hips). Additional findings include thin nose, hair growth delays, and teeth dysplasia. It has been described in two American sisters.
Odontoonychodermal dysplasia is a rare genetic disorder which is characterized by systemic abnormalities of the teeth, the nails of the fingers and toes, the skin, the hair cells, and the sweat glands. It is a type of syndromic ectodermal dysplasia.
Hall-Riggs syndrome is a rare genetic disorder that causes neurological issues and birth defects. People with Hall-Riggs syndrome usually have skeletal dysplasia, facial deformities, and intellectual disabilities. Only 8 cases from 2 families worldwide have been described in medical literature. It is an autosomal recessive genetic disorder, meaning both parents must carry the gene in order for their offspring to be affected.
Ankylosing vertebral hyperostosis with tylosis is a rare autosomal dominant genetic disorder characterized by ossification of the paraspinal ligament, sclerosis of the sacroiliac joint, and punctate hyperkeratosis. Some people with the condition are actually asymptomatic, which means they're relatively unaffected by it, the people who do show symptoms of it usually only show chronic/recurring back pain ranging from mild to moderate and, occasionally, obesity. It has only been described in 8 members of a 2-generation Greek Cypriot family. It is a type of dysostosis.
Faciocardiorenal syndrome is a rare genetic disorder characterized by facial dysmorphisms, congenital heart defects, and the presence of a horseshoe kidney, alongside intellectual disabilities. Facial dysmorphisms include protruding ears, narrowing of the mouth, cleft palate, hypertelorism, etc. Only 4 cases from the United States, Northern Ireland, and Mexico have been described in the medical literature. Transmission is, presumably, autosomal recessive.
