Screening for GNAS genetic and epigenetic alterations in progressive osseous heteroplasia: first Italian series.
Progressive osseous heteroplasia (POH) is a rare autosomal dominant disorder of mesenchymal differentiation characterized by progressive heterotopic ossification (HO) of dermis, deep connective tissues and skeletal muscle. Usually, initial bone formation occurs during infancy as primary osteoma cutis (OC) then progressively extending into deep connective tissues and skeletal muscle over childho...
متن کاملProgressive osseous heteroplasia: a model for the imprinting effects of GNAS inactivating mutations in humans.
CONTEXT Heterozygous GNAS inactivating mutations are known to induce pseudohypoparathyroidism type 1a when maternally inherited and pseudopseudohypoparathyroidism when paternally inherited. Progressive osseous heteroplasia (POH) is a rare disease of ectopic bone formation, and studies in different families have shown that POH is also caused by paternally inherited GNAS mutations. OBJECTIVE Ou...
متن کاملSomitic disruption of GNAS in chick embryos mimics progressive osseous heteroplasia.
Progressive osseous heteroplasia (POH) is a rare developmental disorder of heterotopic ossification (HO) caused by heterozygous inactivating germline mutations in the paternal allele of the GNAS gene. Interestingly, POH lesions have a bewildering mosaic distribution. Using clinical, radiographic, and photographic documentation, we found that most of the 12 individuals studied had a lesional bia...
متن کاملProgressive osseous heteroplasia: diagnosis, treatment, and prognosis
Progressive osseous heteroplasia (POH) is an ultrarare genetic condition of progressive ectopic ossification. Most cases of POH are caused by heterozygous inactivating mutations of GNAS, the gene encoding the alpha subunit of the G-stimulatory protein of adenylyl cyclase. POH is part of a spectrum of related genetic disorders, including Albright hereditary osteodystrophy, pseudohypoparathyroidi...
متن کاملProgressive osseous heteroplasia. Report of a family.
We report a case of progressive osseous heteroplasia in a female infant who had progressive ossification of the skin and deep connective tissues. Isolated dermal ossification is present in her father and younger sister suggesting an autosomal dominant mode of inheritance with variable expressivity or possible somatic mosaicism. This report of a family with progressive osseous heteroplasia contr...
