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 GeneticsDec 20, 2023The c.443C>T (p.A148V) alteration is located in exon 6 (coding exon 6) of the MCMBP gene. This alteration results from a C to T substitution at nucleotide position 443, causing the alanine (A) at amino acid position 148 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
