Genes affected

SPEG (HGNC:16901): (striated muscle enriched protein kinase) This gene encodes a protein with similarity to members of the myosin light chain kinase family. This protein family is required for myocyte cytoskeletal development. Along with the desmin gene, expression of this gene may be controlled by the desmin locus control region. Mutations in this gene are associated with centronuclear myopathy 5. [provided by RefSeq, Jun 2016]

ASIC4-AS1 (HGNC:40960): (ASIC4 antisense RNA 1)

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.49).
• BP6: Variant 2-219483130-G-A is Benign according to our data. Variant chr2-219483130-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 3011221.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=1.73 with no splicing effect.
