<s>[INST] My son is 5 years old and has G6PD enzyme deficiency. He is Asian and we just returned from the beach last night. He has some type of rash all over his back and arms and is itching. His skin has gotten pretty dark this summer from the sun. He is itching a lot. I am trying to decide if he got too much sun this past week of if this is some type of symptom of his blood disorder . He is our adopted son and we are Caucasian so I have a different skin type. It s hard to tell if it is red or yellow, but the whites of his eyes don t seem to be yellow. [/INST] Hello and welcome to Chat Doctor,G-6-PD does not present with rashes on the body. As you have mentioned that your son has had an exposure to sun at the beach recently, the rash is most likely due the sun exposure. The sun burn leads to red skin which later on turn itchy. Your son is also having similar symptoms. Topical application of emollient can relieve the itching. Avoid exposure to sunlight. Maintain HY Chat Doctor.  </s>
