Genes affected

HMGB1 (HGNC:4983): (high mobility group box 1) This gene encodes a protein that belongs to the High Mobility Group-box superfamily. The encoded non-histone, nuclear DNA-binding protein regulates transcription, and is involved in organization of DNA. This protein plays a role in several cellular processes, including inflammation, cell differentiation and tumor cell migration. Multiple pseudogenes of this gene have been identified. Alternative splicing results in multiple transcript variants that encode the same protein. [provided by RefSeq, Sep 2015]

The c.588T>G (p.D196E) alteration is located in exon 5 (coding exon 4) of the HMGB1 gene. This alteration results from a T to G substitution at nucleotide position 588, causing the aspartic acid (D) at amino acid position 196 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
