From NCBI Gene:
This gene is a member of the basic helix-loop-helix family. The encoded protein is a transcription factor involved in limb development. Mutations in this gene have been associated with mesoaxial synostotic syndactyly Malik-Percin type (MSSD). Copy number variation of a locus containing this gene has been linked to a form of split-hand/foot malformation with long bone deficiency (SHFLD3). [provided by RefSeq, Mar 2015]
Transcription factor, which play a role in limb development. Is an essential player in the regulatory network governing transcription of genes implicated in limb morphogenesis.

- Camptosynpolydactyly, complex
- Syndactyly type 9
Camptosynpolydactyly, complex (CCSPD): An autosomal recessive disorder characterized by hand and foot deformities consisting of polydactyly with digits arising from the dorsum of hands, syn- and camptodactyly of some fingers, soft tissue syndactyly of first and second toes, and dysplastic nails. [MIM:607539]
Syndactyly, mesoaxial synostotic, with phalangeal reduction (MSSD): An autosomal recessive, non-syndromic digit anomaly characterized by mesoaxial osseous synostosis at a metacarpal level, reduction of one or more phalanges, hypoplasia of distal phalanges of preaxial and postaxial digits, clinodactyly of fifth fingers, and preaxial fusion of toes. [MIM:609432]
Split-hand/foot malformation with long bone deficiency 3 (SHFLD3): A disease characterized by the association of split-hand/foot malformation with long bone deficiency involving the tibia and fibula. Split-hand/foot malformation is a limb malformation involving the central rays of the autopod. Phenotypic expression is extremely variable between and within families, and even between limbs of a single patient, ranging from syndactyly and oligodactyly to the most severe monodactyly with only a single phalanx. Limb features include median clefts of the hands and feet, and aplasia and/or hypoplasia of the phalanges, metacarpals, and metatarsals. [MIM:612576]
