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]

The c.257A>G (p.Y86C) alteration is located in exon 4 (coding exon 4) of the DYNLRB1 gene. This alteration results from a A to G substitution at nucleotide position 257, causing the tyrosine (Y) at amino acid position 86 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
