Cerebro-costo-mandibular syndrome is a very rare genetic disorder which is characterized by jaw/chin, palate and rib abnormalities. [1]
The following list comprises the most common symptoms people with this disorder exhibit: [2]
Common (but not the most) symptoms include:
Not common but also not rare symptoms include:
This disorder is caused by autosomal dominant mutations in the SNRPB gene, in chromosome 20. [3]
Only 110 cases have been described in medical literature. [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20]
Waardenburg syndrome is a group of rare genetic conditions characterised by at least some degree of congenital hearing loss and pigmentation deficiencies, which can include bright blue eyes, a white forelock or patches of light skin. These basic features constitute type 2 of the condition; in type 1, there is also a wider gap between the inner corners of the eyes called telecanthus, or dystopia canthorum. In type 3, which is rare, the arms and hands are also malformed, with permanent finger contractures or fused fingers, while in type 4, the person also has Hirschsprung's disease. There also exist at least two types that can result in central nervous system (CNS) symptoms such as developmental delay and muscle tone abnormalities.
Mismatch repair cancer syndrome (MMRCS) is a cancer syndrome associated with biallelic DNA mismatch repair mutations. It is also known as Turcot syndrome and by several other names.
Cohen syndrome is a very rare autosomal recessive genetic disorder with varied expression, characterised by obesity, intellectual disability, distinct craniofacial abnormalities and potential ocular dysfunction.
Hajdu–Cheney syndrome, also called acroosteolysis with osteoporosis and changes in skull and mandible, arthrodentoosteodysplasia and Cheney syndrome, is an extremely rare autosomal dominant congenital disorder of the connective tissue characterized by severe and excessive bone resorption leading to osteoporosis and a wide range of other possible symptoms. Mutations in the NOTCH2 gene, identified in 2011, cause HCS. HCS is so rare that only about 50 cases have been reported worldwide since the discovery of the syndrome in 1948
Acrocephalosyndactyly is a group of autosomal dominant congenital disorders characterized by craniofacial (craniosynostosis) and hand and foot (syndactyly) abnormalities. When polydactyly is present, the classification is acrocephalopolysyndactyly. Acrocephalosyndactyly is mainly diagnosed postnatally, although prenatal diagnosis is possible if the mutation is known to be within the family genome. Treatment often involves surgery in early childhood to correct for craniosynostosis and syndactyly.
Hay–Wells syndrome is one of at least 150 known types of ectodermal dysplasia. These disorders affect tissues that arise from the ectodermal germ layer, such as skin, hair, and nails.
Vici syndrome, also called immunodeficiency with cleft lip/palate, cataract, hypopigmentation and absent corpus callosum, is a rare autosomal recessive congenital disorder characterized by albinism, agenesis of the corpus callosum, cataracts, cardiomyopathy, severe psychomotor retardation, seizures, immunodeficiency and recurrent severe infections. To date, about 50 cases have been reported.
PHD finger protein 8 is a protein that in humans is encoded by the PHF8 gene.
Antley–Bixler syndrome is a rare, severe autosomal recessive congenital disorder characterized by malformations and deformities affecting the majority of the skeleton and other areas of the body.
Gerodermia osteodysplastica (GO) is a rare autosomal recessive connective tissue disorder included in the spectrum of cutis laxa syndromes.
Malpuech facial clefting syndrome, also called Malpuech syndrome or Gypsy type facial clefting syndrome, is a rare congenital syndrome. It is characterized by facial clefting, a caudal appendage, growth deficiency, intellectual and developmental disability, and abnormalities of the renal system (kidneys) and the male genitalia. Abnormalities of the heart, and other skeletal malformations may also be present. The syndrome was initially described by Georges Malpuech and associates in 1983. It is thought to be genetically related to Juberg-Hayward syndrome. Malpuech syndrome has also been considered as part of a spectrum of congenital genetic disorders associated with similar facial, urogenital and skeletal anomalies. Termed "3MC syndrome", this proposed spectrum includes Malpuech, Michels and Mingarelli-Carnevale (OSA) syndromes. Mutations in the COLLEC11 and MASP1 genes are believed to be a cause of these syndromes. The incidence of Malpuech syndrome is unknown. The pattern of inheritance is autosomal recessive, which means a defective (mutated) gene associated with the syndrome is located on an autosome, and the syndrome occurs when two copies of this defective gene are inherited.
Floating–Harbor syndrome, also known as Pelletier–Leisti syndrome, is a rare disease with fewer than 50 cases described in the literature. It is usually diagnosed in early childhood and is characterized by the triad of proportionate short stature with delayed bone age, characteristic facial appearance, and delayed speech development. Although its cause is unknown, it is thought to result from genetic mutation, and diagnosis is established by the presence of a heterozygous SRCAP mutation in those with clinical findings of FHS.
Lateral meningocele syndrome, also known as Lehman syndrome, is a very rare skeletal disorder with facial anomalies, hypotonia, and meningocele-related neurologic dysfunction. These protrusions form from membranes surrounding the spinal cord in gaps in the spine (vertebrae). They most often occur in the lower spine and damage the surrounding nerves that spread throughout the rest of the body. Examples of resulting damages are bladder function, prickling or tingling sensations, stiffness and weakness in the legs, and back pain. People affected with lateral meningocele typically have high arched eyebrows, widely spaced eyes, droopy eyes, and other facial features. There have been only 14 reported individuals with lateral meningocele syndrome with 7 of those who have a molecularly confirmed diagnosis. There is no specific treatment for this syndrome, but only supportive management including lateral spinal meningoceles, psychomotor development, musculoskeletal, and routine management.
Nestor-Guillermo progeria syndrome is an extremely rare novel genetic disorder that is part of a group of syndromes called progeria. This disorder is characterized by the same symptoms of other progeria syndromes, which are premature aging with accompanying aged physical appearance, osteolysis, osteoporosis, scoliosis and lipoatrophy, however, what makes this disorder unique from other progeroid syndromes is the absence of any atherosclerotic, cardiovascular, and metabolic symptoms/complications, this makes the life-span of a person with NGPS somewhat longer than the average life-span of someone with progeria itself, although in place of the complications mentioned above, there's also additional symptoms, such as joint stiffness, growth retardation, facial dysmorphisms, wide cranial sutures, micrognathia, atrophic skin and a high risk of developing severe skeletal abnormalities
Otofaciocervical syndrome, also known as Fara Chlupackova syndrome, are a small group of rare developmental disorders of genetic origin which are characterized by facial dysmorphisms, long neck, preauricular and/or branchial pits, cervical muscle hypoplasia, hearing loss, and mild intellectual disabilities. Additional findings include vertebral anomalies and short stature.
Metacarpal synostosis is a rare congenital difference which is characterized by the fusion of 2 metacarpals of the hand, which are usually shortened. It is most commonly seen as a fusion of the 4th and 5th metacarpals. It is a type of non-syndromic syndactyly/synostosis. Autosomal dominant and X-linked recessive inheritance patterns have been reported.
Meacham syndrome is a rare genetic disorder which is characterized by lung, diaphragmatic and genitourinary anomalies.
Spondyloepimetaphyseal dysplasia-short limb-abnormal calcification syndrome is a rare genetic disorder which is characterized by osseous anomalies resulting in short stature and other afflictions.
Splenogonadal fusion-limb defects-micrognathia syndrome, also known by its abbreviation, SGFLD syndrome, is a rare genetic disorder characterized by abnormal fusion of the spleen and the gonad alongside limb defects and orofacial anomalies. It is a type of syndromic dysostosis.
Holoprosencephaly-ectrodactyly-cleft lip/palate syndrome, also simply known as Hartsfield syndrome, is a rare genetic disorder characterized by the presence of variable holoprosencephaly, ectrodactyly, cleft lip and palate, alongside generalized ectodermal abnormalities. Additional findings include endocrine anomalies and developmental delays.
