Genes affected

CAPZA2 (HGNC:1490): (capping actin protein of muscle Z-line subunit alpha 2) The protein encoded by this gene is a member of the F-actin capping protein alpha subunit family. It is the alpha subunit of the barbed-end actin binding protein Cap Z. By capping the barbed end of actin filaments, Cap Z regulates the growth of the actin filaments at the barbed end.

Ambry Genetics

Nov 21, 2022

The c.52G>A (p.A18T) alteration is located in exon 2 (coding exon 2) of the CAPZA2 gene. This alteration results from a G to A substitution at nucleotide position 52, causing the alanine (A) at amino acid position 18 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
