Preferred Label : Acromicric dysplasia;

Symbol : ACMICD;

CISMeF acronym : ACMICD;

Type : Phenotype, molecular basis known;

Description : Acromicric dysplasia is an autosomal dominant disorder characterized by severe short stature, short hands and feet, joint limitations, and skin thickening. Radiologic features include delayed bone age, cone-shaped epiphyses, shortened long tubular bones, and ovoid vertebral bodies. Affected individuals have distinct facial features, including round face, well-defined eyebrows, long eyelashes, bulbous nose with anteverted nostrils, long and prominent philtrum, and thick lips with a small mouth. Other characteristic features include hoarse voice and pseudomuscular build, and there are distinct skeletal features as well, including an internal notch of the femoral head, internal notch of the second metacarpal, and external notch of the fifth metacarpal (summary by Le Goff et al., 2011). Allelic disorders with overlapping skeletal and joint features include geleophysic dysplasia-2 (614185) and the autosomal dominant form of Weill-Marchesani syndrome (608328).;

Inheritance : Autosomal dominant;

Molecular basis : Caused by mutation in the fibrillin 1 gene (FBN1, 134797.0055);

Laboratory abnormalities : Growth cartilage disorganized, with islands of cells and abnormal collagen arrangement;

Prefixed ID : #102370;
