Phenotypes associated with the disease synpolydactyly type 2 (OMIM:608180):
- Metatarsal synostosis (HP:0001440). Evidence: IEA. (OMIM:608180)
- Toe syndactyly (HP:0001770): Webbing or fusion of the toes, involving soft parts only or including bone structure. Bony fusions are referred to as "bony" Syndactyly if the fusion occurs in a radio-ulnar axis. Fusions of bones of the toes in a proximo-distal axis are referred to as "Symphalangism". Evidence: IEA. (OMIM:608180)
- Tarsal synostosis (HP:0008368): Synostosis (bony fusion) involving one or more bones of the tarsus (calcaneus, talus, cuboid, navicular, cuneiiform bones). Evidence: IEA. (OMIM:608180)
- Polydactyly (HP:0010442): A congenital anomaly characterized by the presence of supernumerary fingers or toes. Evidence: IEA. (OMIM:608180)
- Carpal synostosis (HP:0009702): Synostosis (bony fusion) involving one or more bones of the carpus (scaphoid, lunate, triquetrum, trapezium, trapezoid, capitate, hamate, pisiform). Evidence: IEA. (OMIM:608180)
- Metacarpal synostosis (HP:0009701): Fusion involving two or more metacarpal bones (A synostosis of the first metacarpal and the proximal phalanx of the thumb can also be observed, note that the first metacarpal bone corresponds to a proximal phalanx). Evidence: IEA. (OMIM:608180)
- Autosomal dominant inheritance (HP:0000006): 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. Evidence: IEA. (OMIM:608180)
