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)
