While this finding was limited in its scope of number of patients and needs to be validated for the larger FD population, here we assessed two severe FD (S2, S3, ELP1−/−, LAMB4+/−) and three mild FD (M1, M2, M4, ELP1−/−, LAMB4+/+) patient lines. This evidence concerns the gene LAMB4 and Fabry disease.
