Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Definition

A rare primary bone dysplasia characterized by severe mesomelic shortness particularly of the lower limbs with distinctive triangular or rhomboid-shaped tibiae and fibulae, accompanied by bony protuberances and skin dimples. Additional manifestations include radioulnar synostosis, dislocation of the radial head, abnormalities of the hands (such as oligosyndactyly or fusiform-shaped fingers) and feet (pes equinovarus, synostoses of tarsals/metatarsals and phalanges), and dysmorphic facial features. [from ORDO]

Congenital Abnormality
Clubfoot is a congenital limb deformity defined as fixation of the foot in cavus, adductus, varus, and equinus (i.e., inclined inwards, axially rotated outwards, and pointing downwards) with concomitant soft tissue abnormalities (Cardy et al., 2007). Clubfoot may occur in isolation or as part of a syndrome (e.g., diastrophic dysplasia, 222600). Clubfoot has been reported with deficiency of long bones and mirror-image polydactyly (Gurnett et al., 2008; Klopocki et al., 2012).
