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]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• BS2: High AC in GnomAd at 7 AD gene.

Uncertain significance, criteria provided, single submitter	clinical testing	Revvity Omics, Revvity	Aug 04, 2022	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Dec 19, 2023	This sequence change creates a premature translational stop signal (p.Tyr365Thrfs*53) in the CASP10 gene. It is expected to result in an absent or disrupted protein product. However, the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in CASP10 cause disease. This variant is present in population databases (rs781003519, gnomAD 0.004%). 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: 535756). 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. -
