Genes affected
DES (HGNC:2770): (desmin) This gene encodes a muscle-specific class III intermediate filament. Homopolymers of this protein form a stable intracytoplasmic filamentous network connecting myofibrils to each other and to the plasma membrane. Mutations in this gene are associated with desmin-related myopathy, a familial cardiac and skeletal myopathy (CSM), and with distal myopathies. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 32 curated pathogenic missense variants (we use a threshold of 10). The gene has 2 curated benign missense variants. Gene score misZ: 1.7729 (below the threshold of 3.09). Trascript score misZ: 0.36303 (below the threshold of 3.09). GenCC associations: The gene is linked to myofibrillar myopathy 1, dilated cardiomyopathy 1I, atrioventricular block, arrhythmogenic right ventricular cardiomyopathy, dilated cardiomyopathy, familial isolated dilated cardiomyopathy, neurogenic scapuloperoneal syndrome, Kaeser type.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.789
