Genes affected

KDM1B (HGNC:21577): (lysine demethylase 1B) Flavin-dependent histone demethylases, such as KDM1B, regulate histone lysine methylation, an epigenetic mark that regulates gene expression and chromatin function (Karytinos et al., 2009 [PubMed 19407342]).[supplied by OMIM, Oct 2009]

The c.826G>A (p.V276M) alteration is located in exon 11 (coding exon 9) of the KDM1B gene. This alteration results from a G to A substitution at nucleotide position 826, causing the valine (V) at amino acid position 276 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
