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 GeneticsJun 22, 2024The c.1315A>G (p.T439A) alteration is located in exon 12 (coding exon 12) of the MCMBP gene. This alteration results from a A to G substitution at nucleotide position 1315, causing the threonine (T) at amino acid position 439 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
