Genes affected

MCMBP (HGNC:25782): (minichromosome maintenance complex binding protein) This gene encodes a protein which is a component of the hexameric minichromosome maintenance (MCM) complex which regulates initiation and elongation of DNA. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

The c.1027G>A (p.E343K) alteration is located in exon 10 (coding exon 10) of the MCMBP gene. This alteration results from a G to A substitution at nucleotide position 1027, causing the glutamic acid (E) at amino acid position 343 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
