Genes affected
MAPRE2 (HGNC:6891): (microtubule associated protein RP/EB family member 2) The protein encoded by this gene shares significant homology to the adenomatous polyposis coli (APC) protein-binding EB1 gene family. This protein is a microtubule-associated protein that is necessary for spindle symmetry during mitosis. It is thought to play a role in the tumorigenesis of colorectal cancers and the proliferative control of normal cells. Alternative splicing of this gene results in multiple transcript variants.

Likely pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Oct 01, 2018 | Variant summary: MAPRE2 c.169_176delACTATGAG (p.Thr57GlnfsX3) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant was absent in 243540 control chromosomes (gnomAD). To our knowledge, no occurrence of c.169_176delACTATGAG in individuals affected with Symmetric circumferential skin creases, congenital, 2 and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic. - |
