Nothing in this research appears to indicate fault of any kind; rather, a genetic cause.
> Lee’s research team “stumbled” on the discovery after investigating a “gene desert”, a stretch of DNA on chromosome 21 that does not code for proteins, which has previously been linked to IBD and other autoimmune diseases. Writing in Nature, they describe how they found a section of DNA that behaves like a volume control for nearby genes. This “enhancer” was seen only in immune cells called macrophages where it boosted a gene called ETS2 and ramped up the risk of IBD.
As parents we make plenty of real mistakes; blaming ourselves for unavoidable stuff isn't worth adding to the pile.
