Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Disease characteristics

Excerpted from the GeneReview: Disorders of GNAS Inactivation
Disorders of GNAS inactivation include the phenotypes pseudohypoparathyroidism Ia, Ib, and Ic (PHP-Ia, -Ib, -Ic), pseudopseudohypoparathyroidism (PPHP), progressive osseous heteroplasia (POH), and osteoma cutis (OC). PHP-Ia and PHP-Ic are characterized by: End-organ resistance to endocrine hormones including parathyroid hormone (PTH), thyroid-stimulating hormone (TSH), gonadotropins (LH and FSH), growth hormone-releasing hormone (GHRH), and CNS neurotransmitters (leading to obesity and variable degrees of intellectual disability and developmental delay); and The Albright hereditary osteodystrophy (AHO) phenotype (short stature, round facies, and subcutaneous ossifications) and brachydactyly type E (shortening mainly of the 4th and/or 5th metacarpals and metatarsals and distal phalanx of the thumb). Although PHP-Ib is characterized principally by PTH resistance, some individuals also have partial TSH resistance and mild features of AHO (e.g., brachydactyly). PPHP, a more limited form of PHP-Ia, is characterized by various manifestations of the AHO phenotype without the hormone resistance or obesity. POH and OC are even more restricted variants of PPHP: POH consists of dermal ossification beginning in infancy, followed by increasing and extensive bone formation in deep muscle and fascia. OC consists of extra-skeletal ossification that is limited to the dermis and subcutaneous tissues. [from GeneReviews]

Additional description

From OMIM
Progressive osseous heteroplasia is a rare autosomal dominant disorder characterized by dermal ossification beginning in infancy, followed by increasing and extensive bone formation in deep muscle and fascia (Kaplan et al., 1994). The molecular defect causing POH is the same as that causing PPHP: an inactivating GNAS mutation caused only by paternal inheritance of the mutant allele. However, patients with PPHP have a constellation of physical findings referred to as Albright hereditary osteodystrophy (AHO; see 103580) that is often not seen in patients with POH. Bastepe and Juppner (2005) suggested that POH may be an extreme end of the spectrum of the AHO features seen in PPHP.  http://www.omim.org/entry/166350
