Genes affected
MYOZ1 (HGNC:13752): (myozenin 1) The protein encoded by this gene is primarily 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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2022The c.896T>C (p.L299P) alteration is located in exon 6 (coding exon 5) of the MYOZ1 gene. This alteration results from a T to C substitution at nucleotide position 896, causing the leucine (L) at amino acid position 299 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
