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.7528C>G (p.P2510A) alteration is located in exon 51 (coding exon 51) of the PIEZO1 gene. This alteration results from a C to G substitution at nucleotide position 7528, causing the proline (P) at amino acid position 2510 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
