GFER and congenital disorder of glycosylation: In addition to phenotypes related to glycan-binding protein (GBP) staining, there can be potentially at least six glycophenotypes per glycan-related diseases, hence, 1056 possible HPO glycophenotypes terms for the 176 glycan related diseases (congenital disorder of glycosylation (CDG) and diseases where glycophenotypes are detectable, see online supplementary material for Table S1).
