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 GeneticsSep 25, 2023The c.3419G>T (p.R1140I) alteration is located in exon 12 (coding exon 12) of the MCM9 gene. This alteration results from a G to T substitution at nucleotide position 3419, causing the arginine (R) at amino acid position 1140 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
