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.

MAPRE2 Gene-Disease associations (from GenCC):

• skin creases, congenital symmetric circumferential, 2

  Inheritance: AD, Unknown, AR Classification: DEFINITIVE, MODERATE, LIMITED Submitted by: Ambry Genetics, G2P, Labcorp Genetics (formerly Invitae)
• multiple benign circumferential skin creases on limbs

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.898 is higher than 0.05.
