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.

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.3530602).
• BS2: High AC in GnomAdExome4 at 16 AD,BG gene.
