Genes affected

MT-ND4 (HGNC:7459): (mitochondrially encoded NADH dehydrogenase 4) Enables NADH dehydrogenase (ubiquinone) activity. Involved in mitochondrial electron transport, NADH to ubiquinone and mitochondrial respiratory chain complex I assembly. Part of mitochondrial respiratory chain complex I. Implicated in Leber hereditary optic neuropathy; Parkinson's disease; macular degeneration; and schizophrenia. Biomarker of Alzheimer's disease. [provided by Alliance of Genome Resources, Apr 2022]

Three age and sex matched study groups were taken and whole exome sequencing was performed. 1. Healthy Subjects (n=19) 2. Sea Level Venous Thromboembolism (n=15) 3. High Altitude Venous Thromboembolism (n=6) This variant is benign in nature. After analysis we found frequency of rs2853497 in only high altitude induced Thromboembolism study groups. However, this SNP was absent in Healthy Subjects and sea level Thromboembolism study groups. First time it is being reported that there is association of rs2853497with Venous Thromboembolism. -
