Genes affected
SKI (HGNC:10896): (SKI proto-oncogene) This gene encodes the nuclear protooncogene protein homolog of avian sarcoma viral (v-ski) oncogene. It functions as a repressor of TGF-beta signaling, and may play a role in neural tube development and muscle differentiation. [provided by RefSeq, Oct 2009]

The p.Val486Ile variant in SKI has not been previously reported in individuals w ith Shprintzen-Goldberg syndrome, but has been identified in 1/216 Yoruba Africa n chromosomes by the 1000 Genomes Project (dbSNP rs200717031). Computational pre diction tools and conservation analysis do not provide strong support for or aga inst an impact to the protein. In summary, the clinical significance of the p.Va l486Ile variant is uncertain. -
