Summaries for Frontometaphyseal Dysplasia 2

OMIM : 57 Frontometaphyseal dysplasia (FMD) is a progressive sclerosing skeletal dysplasia characterized by supraorbital hyperostosis, undermodeling of the small bones, and small and large joint contractures, as well as extraskeletal developmental abnormalities, primarily of the cardiorespiratory system and genitourinary tract. Patients with FMD2 appear to have a propensity for keloid formation (summary by Wade et al., 2016). For a discussion of genetic heterogeneity of frontometaphyseal dysplasia, see FMD1 (305620). (617137)

MalaCards based summary : Frontometaphyseal Dysplasia 2, also known as fmd2, is related to frontometaphyseal dysplasia. An important gene associated with Frontometaphyseal Dysplasia 2 is MAP3K7 (Mitogen-Activated Protein Kinase Kinase Kinase 7). The drugs Ticlopidine and Ticagrelor have been mentioned in the context of this disorder. Affiliated tissues include bone, skin and testes, and related phenotypes are hypertelorism and low-set ears

UniProtKB/Swiss-Prot : 75 Frontometaphyseal dysplasia 2: A form of frontometaphyseal dysplasia, a progressive sclerosing skeletal dysplasia affecting the long bones and skull. Characteristic features include supraorbital hyperostosis, cranial hyperostosis, undermodeling of the small bones, flared metaphyses, and digital anomalies. Extra-skeletal manifestations include hearing loss, cardiac malformations, and stenosis, particularly of the upper airway and urinary tract. FMD2 inheritance is autosomal dominant.
