Classic progressive supranuclear palsy syndrome (ORPHA:240071)
A classical form of progressive supranuclear palsy (PSP), a rare late-onset neurodegenerative disease, characterized by slowing of vertical saccadic eye movements, falls due to postural instability, axial akinetic-rigid syndrome, and cognitive impairment. Difficulties in speech and swallowing may develop.
Classic pyoderma gangrenosum (ORPHA:538863)
A rare subtype of pyoderma gangrenosum disease characterized by rapidly progressive, single or multiple, painful, aseptic ulcers which present overhanging, violaceous and undermined borders, surrounding induration and erythema, and granulation tissue (occasionally necrotic tissue and/or a purulent exudate) at the base, mainly affecting the legs (but other body surfaces may also be involved), leading to chronic ulcerations and often regressing with cribriform mutilating scars. The disease presents a chronic relapsing course and systemic features (e.g. fever, malaise, arthralgia, myalgia) may be associated.
Classical-like Ehlers-Danlos syndrome type 1 (ORPHA:230839)
A form of Ehlers-Danlos syndrome characterized by generalized joint hypermobility, skin hyperextensibility and easy bruising without atrophic scarring. Other common features include foot and hand deformities (piezogenic papules, pes planus, broad forefeet, brachydactyly, fragile and thin hand skin breaks or bruises easily), severe fatigue and neuromuscular symptoms including muscle weakness and myalgia.
Classical-like Ehlers-Danlos syndrome type 2 (ORPHA:536532)
A rare systemic disease characterized by generalized joint hypermobility with recurrent joint dislocations, redundant and hyperextensible skin with poor wound healing and abnormal scarring, easy bruising, and osteopenia/osteoporosis. Additional manifestations include hypotonia, delayed motor development, foot deformities, prominent superficial veins in the chest region, vascular complications (like mitral valve prolapse and aortic root dilation), hernias, dental anomalies, scoliosis, and facial dysmorphisms (like high palate, micrognathia, narrow palate). Mode of inheritance is autosomal recessive.
CLCN4-related X-linked intellectual disability syndrome (ORPHA:485350)
A rare X-linked syndromic intellectual disability characterized by intellectual disability of variable degree, behavioral anomalies (including autism, mood disorders, obsessive-compulsive behavior, and hetero- and auto-aggression), and epilepsy. Progressive neurological symptoms like movement disorders and spasticity, as well as subtle dysmorphic features have also been reported. Heterozygous females may be as severely affected as males.
Clear cell adenocarcinoma of the ovary (ORPHA:398971)
A rare, malignant, epithelilal ovarian neoplasm, composed of clear, eosinophilic and hobnail cells displaying variable degrees of tubulocystic, papillary and solid histological patterns, macroscopically appearing as a typically unilateral mass in the ovary which ranges from solid to cystic. Patients are often diagnosed in early stages and usually present with pelvic pain and pressure, an abdominal mass and/or gastrointestinal problems, such as early satiety or bloating. Association with Lynch syndrome has been reported.
Clear cell papillary renal cell carcinoma (ORPHA:404511)
Clear cell papillary renal cell carcinoma is a rare, indolent subtype of clear cell renal carcinoma, arising from epithelial cells in the renal cortex. It most frequently manifests with a well-circumscribed, well-encapsulated, unicentric, unilateral, small tumor that typically does not metastasize. Clinically it can present with flank or abdominal pain or hematuria, although most patients are usually asymptomatic at the time of diagnosis. Bilateral and/or multifocal presentation should raise the suspicion of von Hippel-Lindau syndrome.
Clear cell renal carcinoma (ORPHA:319276)
A rare renal tumor arising from proximal tubular epithelial cells of the renal cortex, characterized histologically by malignant epithelial cells with typical clear cytoplasm in conventional staining methods due to a high glycogen and lipid content, featuring a nested growth pattern. Clinically it may present with hematuria, flank pain, anemia or, less commonly, a palpable abdominal mass.
Clear cell sarcoma of kidney (ORPHA:457246)
Clear cell sarcoma of kidney is a rare, primary, genetic renal tumor usually characterized by a unilateral, unicentric, morphologically diverse tumor that arises from the renal medulla and has a tendency for vascular invasion. Clinically it presents with a palpable abdominal mass, abdominal or flank pain, hematuria, anemia and/or fatigue. Metastatic spread to lymph nodes, bones, lungs, retroperitoneum, brain and liver is common at time of diagnosis and therefore bone pain, cough or neurological compromise may be associated. Metastasis to unusual sites, such as the scalp, neck, nasopharynx, axilla, orbits and epidural space, have been reported.
Cleft lip and palate-craniofacial dysmorphism-congenital heart defect-hearing loss syndrome (ORPHA:508476)
A rare genetic multiple congenital anomalies/dysmorphic syndrome without intellectual disability characterized by unilateral or bilateral cleft lip and palate and craniofacial dysmorphism (including frontal bossing, hypertelorism, broad flat nasal bridge, cupped ears/thickened helices, and micrognathia). Additional manifestations are variable congenital cardiac anomalies, pectus excavatum, abnormalities of the hands and feet, ocular abnormalities (myopia, cataract, staphyloma), and conductive or sensorineural hearing loss.
Cleft lip-retinopathy syndrome (ORPHA:1995)
An exceedingly rare association characterized by cleft lip and progressive retinopathy.
Cleft lip/palate-deafness-sacral lipoma syndrome (ORPHA:2003)
Cleft lip/palate-deafness-sacral lipoma syndrome is characterised by cleft lip/palate, profound sensorineural deafness, and a sacral lipoma. It has been described in two brothers of Chinese origin born to non consanguineous parents. Additional findings included appendages on the heel and thigh, or anterior sacral meningocele and dislocated hip. The mode of inheritance is probably autosomal or X-linked recessive.
Cleft lip/palate-ectodermal dysplasia syndrome (ORPHA:3253)
Zlotogora-Ogur syndrome is an ectodermal dysplasia syndrome characterized by hair, skin and teeth anomalies, facial dysmophism with cleft lip and palate, cutaneous syndactyly and, in some cases, intellectual disability.
Epidemiology
The prevalence is unknown but to date, less than 50 cases have been described in the literature. The disorder is frequent on Margarita Island due to a founder effect.
Clinical description
Zlotogora-Ogur syndrome is a congenital disorder characterized by sparse and twisted hair (pili torti) and absent or sparse eyebrows, hypohidrosis, dry skin, palmoplantar keratoderma, abnormal teeth (delayed eruption, microdontia/hypodontia, and anodontia in adults), facial dysmophism (protruding and malformed ears, micrognathia, bilateral cleft lip and palate), cutaneous syndactyly (fingers and toes) and transverse crease on the palms. Onychodystrophy may be present. Additional features including intellectual disability, deafness, hypoplastic lacrimal puncta, nipple anomalies, genitourinary abnormalities (hypoplastic scrotum and presence of the testes in the inguinal canal), and lumbar lordosis may be observed. Zlotogora-Ogur syndrome and Margarita Island ectodermal dysplasia are the same entity.
Etiology
Zlotogora-Ogur syndrome is caused by mutations in the gene PVRL1 (11q23-q24) which encodes nectin-1, the principal receptor used by alpha-herpesviruses to mediate entry into human cells. Although the mechanism underlying the physiopathology of Zlotogora-Ogur syndrome is still unknown, it has been proposed that nectin-1 is a cell-cell adhesion molecule that is preferentially expressed in keratinocytes and that mutations in PVRL1 may abrogate NAP (nectin, afadin, ponsin)-dependent cell-cell adhesion.
Genetic counseling
Transmission is autosomal recessive.

Epidemiology
It has been described in 4 patients so far.
Clinical description
Dysmorphic features include bitemporal narrowing, smooth philtrum, pointed chin and dysmorphic ears. All reported patients had a cleft palate, whereas congenital heart defects or epilepsy are observed in patients with large deletions.
Etiology
Deletions are located within chromosome band 15q14, distal to the Prader-Willi/Angelman region. They were characterized by comparative genomic hybridization (CGH) microarray and fluorescence in situ hybridization (FISH). They have a variable size with the smallest deletion being 1.6 Mb in length.

Cleft palate-large ears-small head syndrome (ORPHA:2013)
Cleft palate-large ears-small head syndrome is a rare, genetic syndrome characterized by cleft palate, large protruding ears, microcephaly and short stature (prenatal onset). Other skeletal abnormalities (delayed bone age, distally tapering fingers, hypoplastic distal phalanges, proximally placed thumbs, fifth finger clinodactyly), Pierre Robin sequence, cystic renal dysplasia, proximal renal tubular acidosis, hypospadias, cerebral anomalies on imaging (enlargement of lateral ventricles, mild cortical atrophy), seizures, hypotonia and developmental delay are also observed.
Cleft palate-lateral synechia syndrome (ORPHA:2016)
Cleft palate-lateral synechia syndrome (CPLS) is a congenital malformation syndrome characterized by the association of cleft palate and intra-oral lateral synechiae connecting the free borders of the palate and the floor of the mouth. CPLS is presumed to be inherited in an autosomal dominant manner.
Epidemiology
11 cases have been reported in the worldwide literature.
Clinical description
Patients present with cleft palate at birth and on examination are found to have multiple cord-like adhesions running from the free internal borders of the palate to the lateral parts of the tongue and floor of the mouth. Babies manifest symptoms of cleft palate such as disrupted sucking and swallowing, recurrent ear infections and speech impairment. Lateral synechiae may be asymptomatic or cause feeding difficulty due to restricted opening of mouth. In some cases the synechiae undergo spontaneous resolution.
Etiology
Etiology is unclear but interposition of the tongue between the palatal shelves in the embryo due to genetic, teratogenic or mechanical insults could result in a cleft palate while close contact between the floor of the mouth and the palate could predispose to the formation of intraoral synechiae. This can be either due to failed regression of buccopharyngeal membrane or formation of subglossopalatal membrane during the 7th week of embryonic life. Less than normal movement of the mandible and tongue is presumed to predispose to the formation of this subglossopalatal membrane.
Diagnostic methods
Diagnosis is clinical. When necessary, computed tomography can help to detect the presence of any bony fusion.
Differential diagnosis
Phenotypic features of CLPS can occur with other congenital anomalies, particularly the Van der Woude (VDW), orofaciodigital syndrome and popliteal pterygium syndrome (see these terms). In one reported family with CPLS, the monozygotic twin of the index case had classic phenotypic features of Fryns syndrome (see this term) suggesting that CPLS may represent a mild phenotypic expression of this syndrome.
Antenatal diagnosis
Prenatal diagnosis of cleft palate can be made by prenatal ultrasonogram.
Genetic counseling
An autosomal dominant inheritance pattern with variable expressivity has been proposed.
Management and treatment
Management includes excision of synechiae and palatal closure. Immediate excision of the synechiae may be necessary due to breathing or feeding problems; obtaining a safe airway for the release of the bands may be difficult. When immediate release of synechiae is not warranted, excision is done during palatal closure. The synechiae has been used to provide additional tissue for the surgical closure of soft palate.
Prognosis
The prognosis depends on the presence of associated anomalies (especially, congenital syngnathia (see this term)), quality of initial repair and regular follow-up.
