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 GeneticsFeb 17, 2022The c.250A>G (p.M84V) alteration is located in exon 3 (coding exon 2) of the MYOZ1 gene. This alteration results from a A to G substitution at nucleotide position 250, causing the methionine (M) at amino acid position 84 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
