Invitae RCV000813722 SCV000954092 uncertain significance Shprintzen-Goldberg syndrome 2018-11-07 criteria provided, single submitter clinical testing This sequence change replaces serine with phenylalanine at codon 28 of the SKI protein (p.Ser28Phe). The serine residue is weakly conserved and there is a large physicochemical difference between serine and phenylalanine. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This variant has been observed in an individual affected with clinical features of SKI-related disease (Invitae). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant disrupts the p.Ser28 amino acid residue in SKI. Other variant(s) that disrupt this residue have been observed in affected individuals (PMID: 24736733), which suggests that this may be a clinically significant amino acid residue. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
