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.1778T>C (p.L593P) alteration is located in exon 15 (coding exon 15) of the MCMBP gene. This alteration results from a T to C substitution at nucleotide position 1778, causing the leucine (L) at amino acid position 593 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
