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.

The c.677A>G (p.K226R) alteration is located in exon 9 (coding exon 9) of the CAPZA1 gene. This alteration results from a A to G substitution at nucleotide position 677, causing the lysine (K) at amino acid position 226 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
