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]

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.68).

BP6

Variant 2-219418576-G-T is Benign according to our data. Variant chr2-219418576-G-T is described in ClinVar as Likely_benign. ClinVar VariationId is 44247.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=0.223 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.000011 (16/1451484) while in subpopulation AFR AF = 0.000453 (15/33078). AF 95% confidence interval is 0.000279. There are 0 homozygotes in GnomAdExome4. There are 8 alleles in the male GnomAdExome4 subpopulation. Median coverage is 92. This position passed quality control check.
