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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 16, 2023The c.10G>A (p.A4T) alteration is located in exon 1 (coding exon 1) of the SPEG gene. This alteration results from a G to A substitution at nucleotide position 10, causing the alanine (A) at amino acid position 4 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
