A-T can cause features of early aging such as premature graying of the hair. It can also cause vitiligo, an auto-immune disease causing loss of skin pigment and resulting in a blotchy “bleach-splashed” look. Warts and molluscum contagiosum, which are viral infections of the skin, can be extensive and resistant to treatment.

A small number of people develop chronic inflammatory skin lesions (granulomas). This may be related to immunization with the measles/mumps/rubella (MMR) vaccine; therefore, the MMR vaccine should not be given to people with A-T. A physician with experience in A-T may need to be consulted for help with treatment.
