Abstract
The cell suicide pathway of apoptosis is a necessary event in the life of multicellular organisms. It is involved in many biological processes ranging from development to the immune response. Over expression of interleukin-1β-converting enzyme (later renamed caspase-1) was shown to be sufficient to induce apoptosis in mammalian cells. The present study aims to assess the gene alterations in the Caspase family of cytochromes so as to derive an association with HNSCC. Earlier eleven genes were found in the human genome to encode 11 human caspases, caspase-1 to caspase-10 and caspase-14, which is now populated to 13, whereas 10 genes were found in the mouse genome to encode 10 murine caspases including caspase-1, 2, 3, 6, 7, 8, 9, 11, 12 and 14 Caspases share a number of features distinguishable from other proteases. The analysis follows an observational study design, employing several computational tools to identify and predict the possible outcomes of gene alterations identified in HNSCC patients. cBioportal server was used to identify the gene alterations which was further analyzed using tools such as PROVEAN, I-Mutant and gnomAD. Several reported polymorphic variants were also identified. The pathogenicity and protein stability of gene alterations documented in the present study were identified at standard biological conditions. Further experimental studies would provide concrete evidence on the association of the observed genetic abnormalities with HNSCC especially in individuals exposed to habitual carcinogens
