What is the complete epigenetic origin which should include the genetic/biological origin and the environment influence related to these disorders of focusing.arrow_forwardPinpointing a disease gene requires a combination of approaches. Mutations in the XIAP gene are known to cause a serious condition called X-linked lymphoproliferative disease (XLPD). In the case of XLPD, in which the blood contains too many lymphocytes (white blood cells of the immune system), crowding out the oxygen-carrying red blood cells and damaging the liver. When compairing the XIAP amino acid sequence of one affected patient to other human and animal standard RefSeq, the patient has an amino acid substitution at position 203, from cystenine (C) to tyrosing (Y). This evolutionary conservation suggests Group of answer choices that the standard RefSeq does not provide enough information to determine a possible cause of XIAP function. mutations in the XIAP gene and XLPD are not associated. that the mutation in the affected patient has no impact on XIAP function. that the mutation in the affected patient might alter XIAP function.arrow_forward
