Genes affected

MYOZ2 (HGNC:1330): (myozenin 2) The protein encoded by this gene belongs to a family of sarcomeric proteins that bind to calcineurin, a phosphatase involved in calcium-dependent signal transduction in diverse cell types. These family members tether calcineurin to alpha-actinin at the z-line of the sarcomere of cardiac and skeletal muscle cells, and thus they are important for calcineurin signaling. Mutations in this gene cause cardiomyopathy familial hypertrophic type 16, a hereditary heart disorder. [provided by RefSeq, Aug 2011]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

This position, referring to a specific DNA site, is a probable branch point but is likely benign (scored 2 / 10, using the threshold of <=3). The score ranges from 0 to 10, with values ≤3 considered benign and >5 classified as pathogenic. Computational evidence support a benign effect (BayesDel_noAF=-0.77).

BP6

Variant 4-119158004-A-G is Benign according to our data. Variant chr4-119158004-A-G is described in ClinVar as Benign. ClinVar VariationId is 31787.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BA1

GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.715 is higher than 0.05.
