Genes affected
RBCK1 (HGNC:15864): (RANBP2-type and C3HC4-type zinc finger containing 1) Enables several functions, including identical protein binding activity; protein sequestering activity; and ubiquitin binding activity. Involved in several processes, including T cell receptor signaling pathway; cellular protein metabolic process; and regulation of DNA-binding transcription factor activity. Part of LUBAC complex. Implicated in glycogen storage disease. [provided by Alliance of Genome Resources, Apr 2022]

Polyglucosan body myopathy type 1 Pathogenic:2
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJun 20, 2023For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 140630). This variant is also known as p.E190fs. This premature translational stop signal has been observed in individual(s) with progressive muscular weakness and cardiomyopathy (PMID: 23889995). This variant is present in population databases (rs730880330, gnomAD 0.03%). This sequence change creates a premature translational stop signal (p.Glu235Glyfs*67) in the RBCK1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RBCK1 are known to be pathogenic (PMID: 2379848, 23104095, 23889995). -
