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.

The c.7561G>C (p.E2521Q) alteration is located in exon 51 (coding exon 51) of the PIEZO1 gene. This alteration results from a G to C substitution at nucleotide position 7561, causing the glutamic acid (E) at amino acid position 2521 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
