“…As a matter of fact, the first symptoms occurred before the age of 18 years in 116 cases, but only 67 patients (57.8%) were diagnosed with MRS before this age [2,3,4,5,10,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39]. Two of the three cases we have reported have been diagnosed under the age of 10; interestingly, literature describes only 18 cases in which diagnosis was made that early [10,14,15,16,17,18,27,31,34,35,37,39].…”
