It is associated with syndromic diseases but can occur as an isolated form. Familial occurrence is assumed in up to 40% of cases, but large-scale studies are lacking. Most of the data are obtained from case reports which postulate autosomal recessive, dominant with reduced penetrance, X-linked, and multifactorial patterns of inheritance. No monogenetic cause has been identified to date. This study was designed to provide basic information on the epidemiology, family history, and comorbidity for a large cohort of isolated PE and to show that there is an inheritance pattern for PE that indicates a genetic background.<\/jats:p>\n                  <jats:p>Materials and Methods\u2003A retrospective study was done using a paper-based questionnaire for all PE patients attending two specialized centers for chest wall deformities. Patients with isolated PE were included and asked to provide information on family history and comorbidities.<\/jats:p>\n                  <jats:p>Results\u2003Family history was available for 78 patients.

Identification of the genetic factors may contribute to characterize patients who are at risk of inheriting isolated
