A unibrow is a single eyebrow created when the two eyebrows meet in the middle above the bridge of the nose. The hair above the bridge of the nose is of the same color and thickness as the eyebrows, such that they converge to form one uninterrupted line of hair.
Saethre–Chotzen syndrome (SCS), also known as acrocephalosyndactyly type III, is a rare congenital disorder associated with craniosynostosis. This affects the shape of the head and face, resulting in a cone-shaped head and an asymmetrical face. Individuals with SCS also have droopy eyelids (ptosis), widely spaced eyes (hypertelorism), and minor abnormalities of the hands and feet (syndactyly). Individuals with more severe cases of SCS may have mild to moderate intellectual or learning disabilities. Depending on the level of severity, some individuals with SCS may require some form of medical or surgical intervention. Most individuals with SCS live fairly normal lives, regardless of whether medical treatment is needed or not.
Abruzzo–Erickson syndrome is an extremely rare disorder characterized by deafness, protruding ears, coloboma, a cleft palate or palatal rugosity, radial synostosis, and short stature. It was first characterized by Abruzzo and Erickson in 1977 as a CHARGE like syndrome as variably expressed among a family of two brothers, their mother, and their maternal uncle. Members of this family exhibited many of the CHARGE symptoms, but notably did not have choanal atresia and the brothers experienced typical genital development. Due to the recent discovery of this disorder, its etiology is not fully known but it is understood that it arises from mutations on the TBX22 gene on the X-chromosome. The disorder is inherited in an X-linked recessive manner. There is currently no known cure but its symptoms can be treated.
Blepharophimosis is a congenital anomaly in which the eyelids are underdeveloped such that they cannot open as far as usual and permanently cover part of the eyes. Both the vertical and horizontal palpebral fissures are shortened; the eyes also appear spaced more widely apart as a result, known as telecanthus.
Aarskog–Scott syndrome (AAS) is a rare disease inherited as X-linked and characterized by short stature, facial abnormalities, skeletal and genital anomalies. This condition mainly affects males, although females may have mild features of the syndrome.
Young–Simpson syndrome (YSS) is a rare congenital disorder with symptoms including hypothyroidism, heart defects, facial dysmorphism, cryptorchidism in males, hypotonia, intellectual disability, and postnatal growth retardation.
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.
Blepharophimosis, ptosis, epicanthus inversus syndrome (BPES) is a rare medical anomaly characterized by the conditions it is named after: blepharophimosis, ptosis and epicanthus inversus. There are two types; type 1 is distinguished from type 2 by including the symptom of premature ovarian insufficiency (POI) in females, which causes menopausal symptoms and infertility in patients as young as 15 years old.
Filippi syndrome, also known as Syndactyly Type I with Microcephaly and Mental Retardation, is a very rare autosomal recessive genetic disease. Only a very limited number of cases have been reported to date. Filippi Syndrome is associated with diverse symptoms of varying severity across affected individuals, for example malformation of digits, craniofacial abnormalities, intellectual disability, and growth retardation. The diagnosis of Filippi Syndrome can be done through clinical observation, radiography, and genetic testing. Filippi Syndrome cannot be cured directly as of 2022, hence the main focus of treatments is on tackling the symptoms observed on affected individuals. It was first reported in 1985.
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.
Camptodactyly, tall stature, and hearing loss syndrome, also known as CATSHL syndrome, is a rare genetic disorder which consists of camptodactyly, tall height, scoliosis, and hearing loss. Occasionally, developmental delay and intellectual disabilities are reported. About 30 (live) people with the disorder have been recorded in medical literature to date ; 27 people from a four-generation Utah family and 2 brothers from consanguineous Egyptian parents. This disorder is caused by autosomal dominant missense mutations in the FGFR3 gene.
Camera–Marugo–Cohen syndrome, also known as Obesity, mental retardation, body asymmetry and muscle weakness syndrome is a very rare genetic disorder which is characterized by familial obesity, intellectual disabilities, body asymmetry, and muscular weakness. It is a type of syndromic obesity/obesity syndrome. 2 cases have been reported in medical literature
Dauwerse–Peters syndrome, also known as Short stature, facial dysmorphism, severe brachydactyly and syndactyly, is an extraordinarily rare novel genetic disorder which is characterized by a short height, depressed nasal bridge, flat facies, upward-slanting eyes, mild nostril anteversion, low-set ears, broad nasal root, severe generalized hand brachydactyly and 2nd-3rd toe syndactyly. Additional features include infertility due to azoospermia, radial and ulnar dysplasia, and pedal symphalangism. This disorder is extremely rare, since only 1 case has been reported in medical literature. This condition is caused by a chromosomal translocation.
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.
Blepharophimosis intellectual disability syndromes are a group of rare genetic disorders which are characterized by blepharophimosis, ptosis, and intellectual disabilities. These disorders usually follow either autosomal recessive, autosomal dominant, x-linked recessive, or mitochondrial inheritance patterns.
Aphalangy-syndactyly-microcephaly syndrome is a very rare limb malformation syndrome which is characterized by agenesis of the distal phalanges, syndactyly, duplication of the fourth metatarsal, microcephaly, and mild intellectual disabilities. Only 6 cases from 4 families in Spain, Turkey and other countries have been reported in medical literature. Transmission is autosomal dominant.
Tucker syndrome, also known as Ptosis-vocal cord paralysis syndrome, is a very rare genetic disorder which is characterized by congenital bilateral ptosis and recurrent laryngeal nerve paresis. Additional findings include short stature. It was described in a small 2-generation family.
Syndactyly-nystagmus syndrome due to 2q31.1 microduplication, also known as 2q31.1 microduplication syndrome, is a rare genetic disorder characterized by syndactyly affecting the third-fourth fingers and bilateral congenital nystagmus.
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.
