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.L397V variant (also known as c.1189C>G), located in coding exon 3 of the SKI gene, results from a C to G substitution at nucleotide position 1189. The leucine at codon 397 is replaced by valine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
