Pedigree diagram of family and chromatograms of AMN mutations in a family with Imerslund-Gräsbeck syndrome. a Pedigree diagram of a sibship with Imerslund-Gräsbeck syndrome. Circles represent females, squares represent males. Full symbols denote patients with IGS, dots equals presumed carrier status. b Chromatograms of 2 novel compound heterozygous mutations in the gene AMN (Genbank NM_030943.3), encoding for the protein amnionless, identified in 2 half-sisters (III-1 and III-2) with Imerslund-Gräsbeck syndrome
