Genes affected
MCM9 (HGNC:21484): (minichromosome maintenance 9 homologous recombination repair factor) The protein encoded by this gene is a member of the mini-chromosome maintenance (MCM) protein family that are essential for the initiation of eukaryotic genome replication. Binding of this protein to chromatin has been shown to be a pre-requisite for recruiting the MCM2-7 helicase to DNA replication origins. This protein also binds, and is a positive regulator of, the chromatin licensing and DNA replication factor 1, CDT1. [provided by RefSeq, Nov 2010]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2021The c.3319C>T (p.R1107C) alteration is located in exon 12 (coding exon 12) of the MCM9 gene. This alteration results from a C to T substitution at nucleotide position 3319, causing the arginine (R) at amino acid position 1107 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
