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]

Apr 13, 2022

The c.598T>C (p.C200R) alteration is located in exon 7 (coding exon 7) of the MCMBP gene. This alteration results from a T to C substitution at nucleotide position 598, causing the cysteine (C) at amino acid position 200 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
