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.345A>C (p.K115N) alteration is located in exon 6 (coding exon 4) of the KDM1B gene. This alteration results from a A to C substitution at nucleotide position 345, causing the lysine (K) at amino acid position 115 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
