RanBP-type and C3HC4-type zinc finger-containing protein 1 is a protein that in humans is encoded by the RBCK1 gene.[3]

The protein encoded by this gene is similar to mouse UIP28/UbcM4 interacting protein. Alternative splicing has been observed at this locus, resulting in distinct isoforms.[3]

Clinical significance

A family quartet was found with two children, both affected with a previously unreported disease, characterized by progressive muscular weakness and cardiomyopathy, with normal intelligence. During the course of the study, one additional unrelated patient was found with a comparable phenotype. From whole-genome sequence data, RBCK1, a gene encoding an E3 ubiquitin-protein ligase, was identified as the most likely candidate gene, with two protein-truncating mutations in probands in the first family. Sanger sequencing identified a private homozygous splice variant in RBCK1 in the proband in the second family, yet SNP genotyping revealed a 1.2Mb copy-neutral region of homozygosity covering RBCK1. RNA-Seq confirmed aberrant splicing of RBCK1 transcripts, resulting in truncated protein products.[4] Ten other individuals with mutations in RBCK1 and overlapping phenotypes have been identified.[5]
