| A rare genetic cerebral malformation characterized by the presence of cortical smoothening with loss of secondary and tertiary gyri, associated with an excessive number of small, irregular gyri with increased cortical thickness, located in the occipital lobes. Patients usually present with seizures (including myoclonic-astatic, absence, atypical absence, vision loss, myoclonic-atonic, generalized tonic-clonic) and variable (absent to moderate) developmental and/or intellectual delay. There is evidence the disease is caused by homozygous or compound heterozygous mutations in the LAMC3 gene on chromosome 9q34. |

| A rare genetic dentin dysplasia disease with characteristics of extreme microdontia, oligodontia and abnormal tooth shape (including globular teeth, incisal notches and double tooth formation). Short roots with a variable pulp phenotype (including taurodontia and flame-shaped pulp) enamel hypoplasia and anterior open bite may also be associated. Caused by homozygous mutation in the SMOC2 gene on chromosome 6q27. |

| A rare genetic multiple congenital anomalies/dysmorphic syndrome with the association of short stature and progressive discrete subaortic stenosis. Additional variable manifestations include upturned nose, voice and vocal cord abnormalities, obstructive lung disease, inguinal hernia, kyphoscoliosis and occasionally epicanthus, strabismus, microphthalmos and widely spaced teeth. There have been no further descriptions in the literature since 1984. |

| A rare genetic multiple congenital anomalies/dysmorphic syndrome with characteristics of craniofacial dysmorphism (midface hypoplasia, depressed nasal bridge, small nose with upturned tip, cleft palate, Pierre Robin sequence), bilateral, pronounced sensorineural hearing loss and skeletal/joint anomalies (including spondyloepiphyseal dysplasia, arthralgia/arthropathy), in the absence of ocular abnormalities. There is evidence the disease is caused by heterozygous mutation in the COL11A2 gene on chromosome 6p21. |

| A rare genetic developmental defect during embryogenesis disorder with characteristics of severe early-onset salt-wasting adrenal insufficiency and ambiguous/female external genitalia (irrespective of chromosomal sex) due to mutations in the CYP11A1 gene. Milder cases may present delayed onset of adrenal gland dysfunction and genitalia phenotype may range from normal male to female in individuals with 46,XY karyotype. Imaging studies reveal hypoplastic/absent adrenal glands and biochemical findings include low serum cortisol, mineralocorticoids, androgens and sodium with elevated potassium levels. Caused by heterozygous, compound heterozygous or homozygous mutation in the CYP11A1 gene on chromosome 15q23-q24. |

Acetabular spurs and phalangeal cone-shaped epiphyses are not present and osseous manifestations tend to normalize with age. There have been no further descriptions in the literature since 1988. |
