Write answer in between .Q:A 3-month-old boy is brought to the pediatrician by his mother after she notices orange sandlike crystalline material in her childs diaper. He is not currently taking any medication and is exclusively breastfed. His immunizations are up to date. The doctor tells the mother that her son may have an X-linked recessive disorder. The boy is prescribed a medication that inhibits an enzyme responsible for the production of the crystals seen in his urine microscopy. Which of the following enzymes is the target of this medication?? A: Hypoxanthine-guanine phosphoribosyltransferase, B: Xanthine oxidase, C: Adenine phosphoribosyltransferase, D: Adenosine deaminase, E: Aminolevulinic acid synthetase,  <response>: This is a clinical vignette describing a 3-month-old boy with orange sand-like crystals in his urine. The description of X-linked recessive inheritance and urine crystals suggests this boy likely has Lesch-Nyhan syndrome. Lesch-Nyhan syndrome is caused by a deficiency in the enzyme hypoxanthine-guanine phosphoribosyltransferase HGPRT. This results in overproduction and accumulation of uric acid. The medication described aims to inhibit the enzyme responsible for producing these uric acid crystals. Therefore, the target enzyme of the medication is likely xanthine oxidase, which catalyzes the formation of uric acid.B: Xanthine oxidase
