Relevance to Autism

Two de novo protein-truncating variants in the SKI gene were identified in ASD probands from the Autism Sequencing Consortium (De Rubeis et al., 2014; Satterstrom et al., 2020), while additional protein-truncating variants in this gene were observed in case and control samples from the Danish iPSYCH study (Satterstrom et al., 2020). TADA analysis of de novo variants from the Simons Simplex Collection and the Autism Sequencing Consortium and protein-truncating variants from iPSYCH in Satterstrom et al., 2020 identified SKI as a candidate gene with a false discovery rate (FDR) between 0.01 and 0.05 (0.01 < FDR 0.05). A de novo missense variant in the SKI gene was also observed in an ASD proband in Yuen et al., 2017.

Molecular Function

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. Heterozygous variants in this gene are associated with Shprintzen-Goldberg syndrome (OMIM 182212), a disorder comprising craniosynostosis, a marfanoid habitus, and skeletal, neurologic, cardiovascular, and connective tissue anomalies.

SFARI Gene Update

We are pleased to announce some changes to the ongoing curation of the data in SFARI Gene. In the context of a continued effort to develop the human gene module and its manually curated list of autism risk genes, we are modifying other aspects of the site to focus on the information that is of greatest interest to the research community. The version of SFARI Gene that has been developed until now will be frozen and will remain available as “SFARI Gene Archive”. Please see the announcement for more details.
