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.188C>T (p.T63M) alteration is located in exon 4 (coding exon 4) of the CAPZA1 gene. This alteration results from a C to T substitution at nucleotide position 188, causing the threonine (T) at amino acid position 63 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
