Genes affected

PLN (HGNC:9080): (phospholamban) The protein encoded by this gene is found as a pentamer and is a major substrate for the cAMP-dependent protein kinase in cardiac muscle. The encoded protein is an inhibitor of cardiac muscle sarcoplasmic reticulum Ca(2+)-ATPase in the unphosphorylated state, but inhibition is relieved upon phosphorylation of the protein. The subsequent activation of the Ca(2+) pump leads to enhanced muscle relaxation rates, thereby contributing to the inotropic response elicited in heart by beta-agonists. The encoded protein is a key regulator of cardiac diastolic function. Mutations in this gene are a cause of inherited human dilated cardiomyopathy with refractory congestive heart failure, and also familial hypertrophic cardiomyopathy. [provided by RefSeq, Apr 2016]

CEP85L (HGNC:21638): (centrosomal protein 85 like) The protein encoded by this gene was identified as a breast cancer antigen. Nothing more is known of its function at this time. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2010]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

PM1

In a topological_domain Cytoplasmic (size 30) in uniprot entity PPLA_HUMAN there are 5 pathogenic changes around while only 0 benign (100%) in NM_002667.5

PM5

Other missense variant is known to change same aminoacid residue: Variant chr6-118558994-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 202040.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.62444 (below the threshold of 3.09). Trascript score misZ: -0.41852 (below the threshold of 3.09). GenCC associations: The gene is linked to hypertrophic cardiomyopathy 18, intrinsic cardiomyopathy, dilated cardiomyopathy 1P, arrhythmogenic right ventricular cardiomyopathy, familial isolated dilated cardiomyopathy.

BS2

High AC in GnomAdExome4 at 16 AD gene.
