Orofaciodigital syndrome I

Oral-facial-digital syndrome type I (OFD1) is usually male lethal during gestation and predominantly affects females. OFD1 is characterized by the following features: Oral (lobulated tongue, tongue nodules, cleft of the hard or soft palate, accessory gingival frenulae, hypodontia, and other dental abnormalities). Facial (widely spaced eyes or telecanthus, hypoplasia of the alae nasi, median cleft or pseudocleft upper lip, micrognathia). Digital (brachydactyly, syndactyly, clinodactyly of the fifth finger; duplicated hallux [great toe]). Kidney (polycystic kidney disease). Brain (e.g., intracerebral cysts, agenesis of the corpus callosum, cerebellar agenesis with or without Dandy-Walker malformation). Intellectual disability (in ~50% of individuals). [from GeneReviews]

Desmosterolosis

Desmosterolosis is a rare autosomal recessive disorder characterized by multiple congenital anomalies and elevated levels of the cholesterol precursor desmosterol in plasma, tissue, and cultured cells (summary by Waterham et al., 2001). [from OMIM]

Fibrous dysplasia of jaw

Cherubism is a childhood-onset, autoinflammatory bone disease characterized by bilateral and symmetric proliferative fibroosseous lesions limited to the mandible and maxilla. The enlargement is usually symmetric in nature. The phenotype ranges from no clinical manifestations to severe mandibular and maxillary overgrowth with respiratory, vision, speech, and swallowing problems. In most affected persons, teeth are displaced, unerupted, unformed, or absent, or may appear to be floating in cystlike spaces; malocclusion, premature exfoliation of deciduous teeth, and root resorption have also been reported. The course and duration of the active process of bone destruction varies between affected individuals; the onset is usually in early childhood, and typically new lesions can occur until puberty. Regression of the lesions occurs as they become filled with bone and remodel during the second and third decade of life. By age 30 years, the facial abnormalities associated with cherubism are not usually recognizable and residual deformity of the jaws is rare. Typically, cherubism is an isolated benign condition; the affected person has normal intellectual skills and is without other physical anomalies. [from GeneReviews]

Lathosterolosis

Lathosterolosis (LATHOS) is an autosomal recessive disorder characterized by a recognizable pattern of multiple congenital anomalies involving axial and appendicular skeleton, liver, central nervous and urogenital systems, and lysosomal storage. It is caused by a defect of cholesterol biosynthesis due to sterol C5-desaturase deficiency (summary by Rossi et al., 2007). [from OMIM]

Pallister-Killian syndrome

Pallister-Killian syndrome (PKS) is a dysmorphic condition involving most organ systems, but is also characterized by a tissue-limited mosaicism; most fibroblasts have 47 chromosomes with an extra small metacentric chromosome, whereas the karyotype of lymphocytes is normal. The extra metacentric chromosome is an isochromosome for part of the short arm of chromosome 12: i(12)(p10) (Peltomaki et al., 1987; Warburton et al., 1987). [from OMIM]

Pelviscapular dysplasia

Syndrome with characteristics of pelviscapular dysplasia with epiphyseal abnormalities, congenital dwarfism and facial dysmorphism. The facial dysmorphism has manifestations of frontal bossing, hypertelorism, narrow palpebral fissures, deep-set eyes, strabismus, low-set posteriorly rotated and malformed ears, dysplasia of conchae, a small chin, a short neck with redundant skin folds, and a low hairline. Intelligence may vary from normal to moderately impaired. Radiographic features comprise aplasia of the body of the scapula, hypoplasia of the iliac bone, humeroradial synostosis, dislocation of the femoral heads, and moderate brachydactyly. Mutations in the TBX15 gene have been identified as potentially causative. Pelviscapular dysplasia is phenotypically similar to pelvis-shoulder dysplasia. [from SNOMEDCT_US]

Lethal polymalformative syndrome, Boissel type

Growth retardation, developmental delay, and facial dysmorphism (GDFD) is an autosomal recessive multiple congenital anomaly syndrome characterized by severe psychomotor retardation, poor overall growth, and dysmorphic facial features. Additional features may include cardiac malformations and deafness (summary by Daoud et al., 2016). [from OMIM]

Microcephaly, growth deficiency, seizures, and brain malformations

Microcephaly, growth deficiency, seizures, and brain malformations (MIGSB) is a severe autosomal recessive disorder characterized by intrauterine growth retardation, postnatal growth deficiency with severe microcephaly, and poor or absent psychomotor development. Additional features include optic atrophy, early-onset seizures, dysmorphic facial features, and brain malformations, such as partial agenesis of the corpus callosum and simplified gyration (summary by Shaheen et al., 2015). [from OMIM]

Mullerian derivatives-lymphangiectasia-polydactyly syndrome

A rare genetic disease characterized by the presence of Müllerian duct derivatives (rudimentary uterus, fallopian tubes, and atretic vagina) and other genital anomalies (cryptorchidism, micropenis) in male newborns, intestinal and pulmonary lymphangiectasia, protein-losing enteropathy, hepatomegaly, and renal anomalies. Postaxial polydactyly, facial dysmorphism (including broad nasal bridge, bulbous nasal tip, long and prominent upper lip with smooth philtrum, hypertrophic alveolar ridges, and mild retrognathia, among other features), and short limbs have also been described. The syndrome is fatal in infancy. [from ORDO]

Neurodevelopmental disorder with short stature, prominent forehead, and feeding difficulties

Neurodevelopmental disorder with short stature, prominent forehead, and feeding difficulties (NEDSFF) is an autosomal recessive disorder characterized by distinct craniofacial features, multisystem dysfunction, profound neurodevelopmental delays, and neonatal death (Shankar et al., 2022). [from OMIM]

Ferro-cerebro-cutaneous syndrome

A rare genetic metabolic liver disease with characteristics of progressive neurodegeneration, cutaneous abnormalities including varying degrees of ichthyosis or seborrheic dermatitis, and systemic iron overload. Patients manifest with infantile-onset seizures, encephalopathy, abnormal eye movements, axial hypotonia with peripheral hypertonia, brisk reflexes, cortical blindness and deafness, myoclonus and hepato/splenomegaly, as well as oral manifestations including microdontia, widely spaced and pointed teeth with delayed eruption and gingival overgrowth. [from SNOMEDCT_US]
