TOMM40 codes for a protein that is embedded into outer membranes of mitochondria and is required for the movement of proteins into mitochondria. More precisely, TOMM40 is the channel-forming subunit of a translocase of the mitochondrial outer membrane (TOM) that is essential for protein transport into mitochondria.[7]
Clinical significance[]
In humans, certain alleles of this gene have been statistically associated with an increased risk of developing late-onset Alzheimer's disease.[8][9] One study has found that TOMM40 risk alleles appears twice as often in people with Alzheimer's disease than those without it.[10] Because TOMM40 is located on chromosome 19, and is closely adjacent to APOE,[6] another gene known to be associated with Alzheimer's, another study has suggested that the statistically significant correlation of TOMM40 with Alzheimer's is due to linkage disequilibrium.[11][12]
