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 made for transcript

Verdict is Benign. Variant got -20 ACMG points.

BP4
This position, referring to a specific DNA site, is a probable branch point but is likely benign (scored 1 / 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=-0.8).
BP6
Variant 2-219420057-C-T is Benign according to our data. Variant chr2-219420057-C-T is described in ClinVar as [Benign]. Clinvar id is 258491.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr2-219420057-C-T is described in Lovd as [Benign].
BA1
GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.794 is higher than 0.05.
