Proximal symphalangism

MedGen UID:: 348856
•Concept ID:: C1861385
•: Disease or Syndrome

Synonyms:	CUSHING SYMPHALANGISM; Cushing's symphalangism; Hereditary absence of proximal interphalangeal joints; HEREDITARY ABSENCE OF THE PROXIMAL INTERPHALANGEAL JOINTS; Proximal symphalangism (disease); Strasburger-Hawkins-Eldridge syndrome; Strasburger-Hawkins-Eldridge-Hargrave-McKusick syndrome; Vessel's syndrome
SNOMED CT:	Symphalangism Cushing type (1162837001); Proximal interphalangeal joint symphalangism Cushing type (1162837001)
Modes of inheritance:	Autosomal dominant inheritance MedGen UID: 141047 •Concept ID: C0443147 • 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. Autosomal dominant inheritance (Orphanet)

MedGen UID:: 331348
•Concept ID:: C1832708
•: Disease or Syndrome

Multiple synostoses syndrome-2 (SYNS2) is an autosomal dominant disorder characterized by progressive joint fusions of the fingers, wrists, ankles, and cervical spine; characteristic facies, including a broad hemicylindrical nose; and progressive conductive hearing loss (summary by Dawson et al., 2006). For a general phenotypic description and a discussion of genetic heterogeneity of multiple synostoses syndrome, see SYNS1 (186500).
