Genes affected
PIEZO1 (HGNC:28993): (piezo type mechanosensitive ion channel component 1 (Er blood group)) The protein encoded by this gene is a mechanically-activated ion channel that links mechanical forces to biological signals. The encoded protein contains 36 transmembrane domains and functions as a homotetramer. Defects in this gene have been associated with dehydrated hereditary stomatocytosis.
