Description : Primary hypertrophic osteoarthropathy is a familial disorder characterized by digital clubbing and osterarthropathy, with variable features of pachydermia, delayed closure of the fontanels, and congenital heart disease. Secondary hypertrophic osteoarthropathy, or pulmonary hypertrophic osteoarthropathy, is a different disorder characterized by digital clubbing secondary to acquired diseases, most commonly intrathoracic neoplasm (Uppal et al., 2008). Touraine et al. (1935) recognized pachydermoperiostosis as a familial disorder with 3 clinical presentations or forms: a complete form characterized by periostosis and pachydermia; an incomplete form with bone changes but without pachydermia; and a 'forme fruste' with pachydermia and minimal skeletal changes. - Genetic Heterogeneity;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the 15-alpha-hydroxyprostaglandin dehydrogenase gene (HPGD, 601688.0001).;

Laboratory abnormalities : Increased urinary prostaglandin E2;

Prefixed ID : #259100;
