Abstract

Progressive osseous heteroplasia (POH) is a rare autosomal-dominant hereditary bone disorder caused by inactivating pathogenic variants in GNAS1. POH is characterized by progressive cutaneous ossification and heterotopic ossification in skeletal muscles and subdermal connective tissues. Understanding of the natural history and phenotypic heterogeneity of the illness is incomplete. We report 2 affected male subjects with a milder than usual clinical course, highlight their clinical presentations and molecular correlates, and propose sodium 18F-fluorine positron emission tomography (PET) scanning as a sensitive technique for POH diagnosis and management.

迟发性进行性骨异质增生:2例不相关病例及使用正电子发射断层扫描诊断。
进行性骨异质增生(POH)是一种罕见的常染色体显性遗传性骨疾病,由GNAS1致病性变异体失活引起。POH的特点是进行性皮肤骨化和骨骼肌和真皮下结缔组织的异位骨化。对该疾病的自然史和表型异质性的了解尚不完整。我们报告了2例受影响的男性受试者,其临床表现比通常的临床病程轻,强调了他们的临床表现和分子相关性,并提出了18f -氟钠正电子发射断层扫描(PET)扫描作为POH诊断和治疗的敏感技术。
