Ever see tattoos of what some people call the “symbol for VHL”? That blue interlocking pattern with four dots is actually the logo of VHL Alliance.. Recently, the original was slightly modernized: “… two shades of blue emphasize the word VHL. In addition, the four dots in the symbol are now in the lighter blue shade, helping to emphasize the multiple stakeholders which include:  patients/caregivers/friends,  healthcare professionals,  researchers, and  the general public.” *
For example, in the tattoo shown in the photo, this person assigned the same logo’s interlocking pattern as “helping hands” and the four dots as 4 family members. - VHL Canada “Patient-Family Quotes" website link.
