RAD50 encodes a DNA-repair protein. The surrounding genomic region also contains regulatory elements relevant to the nearby IL4, IL5 and IL13 cluster, so a locus association can concern more than the coding function of one gene.

TGFB1 encodes transforming growth factor beta 1, which has roles in immune regulation, tissue repair and extracellular-matrix production. Its effects can include both regulation of inflammation and promotion of fibrosis.

TNFRSF10A encodes death receptor 4, or DR4, a receptor that can receive the TRAIL signal and participate in regulated cell-death pathways. TRAIL itself is encoded by TNFSF10.

TNFSF10 encodes TRAIL, a signaling protein involved in regulated cell death through particular receptors. It is a different member of the TNF-related signaling family from TNF itself.

PURSER WELLNESSThe Master MTHFR Protocol Dr. Purser DesignedFrom the reading room

Your local doctor will likely tell you that MTHFR testing and taking an MTHFR Daily supplement is a waste of money. They might even claim it isn't a real medical issue. After 15 years of hearing this pap, I can tell you they are flat-out wrong . Every day that I run into abject medical ignorance—where medicine arrogantly refuses to bend to the hard truth of proven science—I remember Ignaz Semmelweis. Semmelweis died a broken pauper in an asylum, his life destroyed by the conventional doctors of his generation who refused to accept handwashing. Their dismissive attitude today stems not from mal
