Brachydactyly is a medical term which literally means 'short finger'. The shortness is relative to the length of other long bones and other parts of the body. Brachydactyly is an inherited, dominant trait. It most often occurs as an isolated dysmelia, but can also occur with other anomalies as part of many congenital syndromes. Brachydactyly may also be a signal that one is at risk for congenital heart disease due to the association between congenital heart disease and carpenter's syndrome and the link between carpenter's syndrome and brachydactyly.
Microcephaly is a medical condition involving a smaller-than-normal head. Microcephaly may be present at birth or it may develop in the first few years of life. Brain development is often affected; people with this disorder often have an intellectual disability, poor motor function, poor speech, abnormal facial features, seizures and dwarfism.
Dubowitz syndrome is a rare genetic disorder characterized by microcephaly, stunted growth, and a receding chin. Symptoms vary among patients, but other characteristics include a soft, high-pitched voice, partial webbing of the fingers and toes, palate deformations, genital abnormalities, language difficulties, and an aversion to crowds. The pathogenesis of the disease is yet to be identified, and no medical tests can definitively diagnose the disease. The primary method of diagnosis is to identify facial phenotypes. Since it was first described in 1965 by English physician Victor Dubowitz, over 140 cases have been reported worldwide. Although the majority of cases have been reported from the United States, Germany, and Russia, the disorder appears to affect both genders and all ethnicities equally.
CAMFAK syndrome is an acronym used to describe a rare inherited neurologic disease, characterized by peripheral and central demyelination of nerves, similar to that seen in Cockayne syndrome. The name "CAMFAK" comes from the first letters of the characteristic findings of the disease: cataracts, microcephaly, failure to thrive, and kyphoscoliosis. The disease may occur with or without failure to thrive and arthrogryposis.
Marden–Walker syndrome (MWS) is a rare autosomal recessive congenital disorder. It is characterized by blepharophimosis, microcephaly, micrognathia, multiple joint contractures, arachnodactyly, camptodactyly, kyphoscoliosis and delayed motor development and is often associated with cystic dysplastic kidneys, dextrocardia, Dandy–Walker malformation and agenesis of corpus callosum.
Stimmler syndrome is a rare autosomal recessive congenital disorder first described by Stimmler et al. in 1970. It is characterized by dwarfism, diabetes, a small head, and high levels of alanine in the urine.
Heart-hand syndromes are a group of rare diseases that manifest with both heart and limb deformities.
Achalasia microcephaly syndrome is a rare condition whereby achalasia in the oesophagus manifests alongside microcephaly and mental retardation. This is a rare constellation of symptoms with a predicted familial trend.
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.
Fibular aplasia-ectrodactyly syndrome is a very rare genetic disorder which is characterized by aplasia/hypoplasia of the fibula, ectrodactyly, and/or brachydactyly/syndactyly. Additional symptoms include shortness of the femur and tibial/knee/hip/ankle defects. This disorder is inherited in an autosomal dominant manner.
Brachydactyly-long thumb syndrome is a very rare genetic disorder which is characterized by symmetric brachydactyly of the fingers accompanied by an abnormally long thumb, hypomobility of the shoulder and metacarpo-phalangeal joints, and heart conduction defects. Small feet and hands, small shoulders accompanied with short clavicles, clinodactyly, pectus excavatum, mild limb shortening, cardiomegaly, and pulmonic stenosis murmur have also been reported. It was first discovered when D W Hollister et al. described 4 affected members belonging to a 3-generation family. No new cases have been reported since 1981. This disorder is inherited in an autosomal dominant manner.
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.
Heart-hand syndrome, Spanish type, also known as heart-hand syndrome type 3 or III, is a very rare genetic disorder which is characterized by heart, hand, and sometimes feet abnormalities. It is a type of heart-hand syndrome, a class of genetic disorders characterized by cardiac malformations and hand malformations. Only one family with the disorder has been reported in medical literature.
Acro-oto-radial syndrome, also known as Pseudopapilledema blepharophimosis hand anomalies syndrome is a very rare hereditary disorder which is characterized by pseudopapilledema, hearing loss, cranio-facial dysmorphisms and hand/foot anomalies. Unlike other genetic syndromes, people with this syndrome don't exhibit intellectual disabilities. Only 4 cases have been reported in medical literature.
Cyprus facial neuromusculoskeletal syndrome is a rare autosomal dominant genetic disorder characterized by a "mephistophelian" appearance consisting of a ridged, thick triangular skin fold extending from the glabella up into the anterior fontanel, alongside other symptoms such as hypertelorism, widow's peak, low-set ears, kyphoscoliosis congenita, congenital clubfoot, hip dislocation, and arthrogryposis. Additional findings include cataracts, decreased articular range of motion, ptosis, and ankylosis, and, less commonly, mild sensory deficits with muscle weakness and atrophy. It has been described in a large 3-generation Greek Cypriot family.
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.
Severe intellectual disability-progressive spastic diplegia syndrome is a rare novel genetic disorder characterized by severe intellectual disabilities, ataxia, craniofacial dysmorphisms, and muscle spasticity. It is a type of autosomal dominant syndromic intellectual disability.
Ventricular extrasystoles with syncopal episodes-perodactyly-Robin sequence syndrome is a rare autosomal dominant genetic disorder characterized by cardiofaciodigital anomalies occurring alongside Pierre Robin sequence. Additional features include abnormal sense of smell, camptodactyly, recurrent joint dislocations, and short stature. Around 6 to 12 cases have been described in medical literature.
