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]

Shprintzen-Goldberg syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 03, 2017In summary, this variant has uncertain impact on SKI function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with a SKI-related disease. This variant is present in population databases (rs371268096, ExAC 0.002%). This sequence change replaces leucine with phenylalanine at codon 397 of the SKI protein (p.Leu397Phe). The leucine residue is moderately conserved and there is a small physicochemical difference between leucine and phenylalanine. -
