The correct answer is > D increase atopy

the serum level values in this case are all normal execpt for IgA which is low , patients of selective IgA deficiency which have an increased amount of atopic allergy it seems that because their inability to produce IgA they isotype to IgE more frequently

it can,t be contact dermatitis as it is a type od DTH ( delayed type hypersenstivity) depending on T helper cells , macrophages and cytotoxic lymphocytes and not increase in IgA deficiences

immune complex disease > it not corrected as it is realted with complement difiecncies

partial albinism >> have nothing to do with such case as it related to chediak higashi syndrome
