It is a result of heterogeneous alterations in one of five genes that encode red blood cell (RBC) membrane proteins involved in vertical associations that link the membrane cytoskeleton to the lipid bilayer. 2020-10-22 · Hereditary spherocytosis (HS) is an inherited abnormality of the red blood cell, caused by defects in structural membrane proteins. The condition is dominantly inherited in 75% of people. The severity of the disorder is related to the type and amount of membrane disruption, which is genetically determined. The abnormal cells are spherical. A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes.
