Genes affected

MYOZ3 (HGNC:18565): (myozenin 3) The protein encoded by this gene is specifically expressed in the skeletal muscle, and belongs to the myozenin family. Members of this family function as calcineurin-interacting proteins that help tether calcineurin to the sarcomere of cardiac and skeletal muscle. They play an important role in modulation of calcineurin signaling. [provided by RefSeq, Apr 2012]

The c.418G>A (p.A140T) alteration is located in exon 5 (coding exon 4) of the MYOZ3 gene. This alteration results from a G to A substitution at nucleotide position 418, causing the alanine (A) at amino acid position 140 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
