Summaries for Synpolydactyly

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 93403Disease definitionSyndactyly type 2 or synpolydactyly (SPD) is a rare congenital distal limb malformation characterized by the combination of syndactyly and polydactyly.EpidemiologyThe prevalence is unknown.Clinical descriptionIn most cases, SPD affects the 3rd and 4th fingers and the 4th and 5th toes, bilaterally. Additional features include 5th finger clinodactyly, camptodactyly and/or brachydactyly.EtiologyThree loci have been identified: SPD1(HOXD13 gene, 2q31 locus), SPD2 (FBLN1 gene; 22q13.31) and SPD3 (14q11.2-q12).Genetic counselingSPD is inherited in an autosomal dominant manner.Visit the Orphanet disease page for more resources.

MalaCards based summary : Synpolydactyly, also known as syndactyly type 2, is related to synpolydactyly 1 and synpolydactyly 2. An important gene associated with Synpolydactyly is HOXD13 (Homeobox D13). The drugs Pembrolizumab and Ergocalciferol have been mentioned in the context of this disorder. Affiliated tissues include bone, and related phenotypes are abnormality of the metacarpal bones and short foot

Disease Ontology : 12 A syndactyly characterized by an increased number of digits; often a result of a mutation in the HOX D13 gene.

Wikipedia : 76 Syndactyly (from Greek συν- meaning \"together\" and δακτυλος meaning \"finger\") is a condition wherein... more...
