In newborn screening, 599,711 newborns were screened by December 2018, and 57 newborns from 54 families with 26 FD\u2010associated variants were detected. In high\u2010risk screening, 18,235 individuals who had symptoms and\/or a family history of FD were screened by March 2019, and 236 individuals from 143 families with 101 FD\u2010associated variants were detected. Totally 3, 116 variants were detected; 41 of these were not registered in Fabry\u2010database.org or ClinVar and 33 were definitely novel.
