Genes affected

CAPZA1 (HGNC:1488): (capping actin protein of muscle Z-line subunit alpha 1) CAPZA1 is a member of the F-actin capping protein alpha subunit family. This gene encodes the alpha subunit of the barbed-end actin binding protein. The protein regulates growth of the actin filament by capping the barbed end of growing actin filaments.
