Genes affected
DYNLRB1 (HGNC:15468): (dynein light chain roadblock-type 1) This gene is a member of the roadblock dynein light chain family. The encoded cytoplasmic protein is capable of binding intermediate chain proteins, interacts with transforming growth factor-beta, and has been implicated in the regulation of actin modulating proteins. Upregulation of this gene has been associated with hepatocellular carcinomas, suggesting that this gene may be involved in tumor progression. Alternative splicing results in multiple transcript variants. Pseudogenes of this gene have been defined on chromosomes 12 and 18. [provided by RefSeq, Aug 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.88A>G (p.I30V) alteration is located in exon 3 (coding exon 3) of the DYNLRB1 gene. This alteration results from a A to G substitution at nucleotide position 88, causing the isoleucine (I) at amino acid position 30 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
