Genes affected

CASP10 (HGNC:1500): (caspase 10) This gene encodes a protein which is a member of the cysteine-aspartic acid protease (caspase) family. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes which undergo proteolytic processing at conserved aspartic residues to produce two subunits, large and small, that dimerize to form the active enzyme. This protein cleaves and activates caspases 3 and 7, and the protein itself is processed by caspase 8. Mutations in this gene are associated with type IIA autoimmune lymphoproliferative syndrome, non-Hodgkin lymphoma and gastric cancer. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Apr 2011]

DNA sequence analysis of the CASP10 gene demonstrated a sequence change, c.953G>A, in exon 9 that results in an amino acid change, p.Gly318Glu. This sequence change does not appear to have been previously described in patients with CASP10-related disorders and has been described in the gnomAD database with a population frequency of 0.054% in the non-Finish European subpopulation (dbSNP rs138931498). The p.Gly318Glu change affects a highly conserved amino acid residue located in a domain of the CASP10 protein that is known to be functional. In-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL) provide contradictory results for the p.Gly318Glu substitution. Due to these contrasting evidences and the lack of functional studies, the clinical significance of the p.Gly318Glu change remains unknown at this time. -

This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 318 of the CASP10 protein (p.Gly318Glu). This variant is present in population databases (rs138931498, gnomAD 0.06%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with CASP10-related conditions. ClinVar contains an entry for this variant (Variation ID: 535758). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CASP10 protein function with a negative predictive value of 80%. 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. -
