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.545G>T (p.R182L) alteration is located in exon 6 (coding exon 5) of the MYOZ3 gene. This alteration results from a G to T substitution at nucleotide position 545, causing the arginine (R) at amino acid position 182 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
