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.

Submissions by phenotype

PIEZO1-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesDec 21, 2023The PIEZO1 c.3350C>T variant is predicted to result in the amino acid substitution p.Ser1117Leu. This variant was reported with another variant in PIEZO1 in an individual with dehydrated hereditary stomatocytosis (Andolfo et al. 2013. PubMed ID: 23479567). This variant is reported in 0.0035% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
