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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 11, 2022The c.416C>T (p.T139M) alteration is located in exon 5 (coding exon 5) of the MCMBP gene. This alteration results from a C to T substitution at nucleotide position 416, causing the threonine (T) at amino acid position 139 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
