A rare genetic bone development disorder characterized by occipital and parietal bone hypoplasia leading to occipital encephalocele, calvarial mineralization defects, craniosynostosis, radiohumeral fusions, oligodactyly and other skeletal anomalies (arachnodactyly, terminal phalangeal aplasia of the thumbs, bilateral absence of the great toes, pronounced bilateral angulation of femora, shortened limbs, advanced osseous maturation). Fetal death in utero is associated. There is evidence the disease can be caused by homozygous mutation in the CYP26B1 gene on chromosome 2p13. |

A very rare and complex hamartomatous overgrowth disorder with characteristics of progressive overgrowth of the skeleton, skin, adipose, and central nervous systems. Neonates usually appear normal at birth. Onset usually occurs from 6-18 months of age with asymmetric overgrowth seen mainly in the hands or feet. Causal mutations have been reported in two components of the phosphatidylinositol 3-kinase (PI3K)-AKT pathway: PTEN and AKT1. The AKT1 mutation is a somatic mosaic. PTEN mutations have been reported both in the constitutive DNA and as somatic mosaic mutations. The disease is not inherited in those with a somatic AKT1 de novo mutation; PTEN mutations are inherited autosomal dominantly. |

SHOX-related short stature is a primary bone dysplasia characterized by a height that is 2 standard deviations below the corresponding mean height for a given age, sex and population group, in the absence of obvious skeletal abnormalities and other diseases and with normal developmental milestones. Patients present normal bone age with normal limbs, shortening of the extremities (significantly lower extremities-trunk and sitting height-to-height ratios), normal hGH values, normal karyotype, and Leri-Weill dyschondrosteosis-like radiological signs (e.g. triangularization of distal radial epiphyses, pyramidalization of distal carpal row, and lucency of the distal radius on the ulnar side). Mesomelic disproportions and Madelung deformity are not apparent at a young age but may develop later in life or never. |
