Genes affected

GADD45B (HGNC:4096): (growth arrest and DNA damage inducible beta) This gene is a member of a group of genes whose transcript levels are increased following stressful growth arrest conditions and treatment with DNA-damaging agents. The genes in this group respond to environmental stresses by mediating activation of the p38/JNK pathway. This activation is mediated via their proteins binding and activating MTK1/MEKK4 kinase, which is an upstream activator of both p38 and JNK MAPKs. The function of these genes or their protein products is involved in the regulation of growth and apoptosis. These genes are regulated by different mechanisms, but they are often coordinately expressed and can function cooperatively in inhibiting cell growth. [provided by RefSeq, Jul 2008]

The c.463A>G (p.I155V) alteration is located in exon 4 (coding exon 4) of the GADD45B gene. This alteration results from a A to G substitution at nucleotide position 463, causing the isoleucine (I) at amino acid position 155 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
