Genes affected

MAPRE1 (HGNC:6890): (microtubule associated protein RP/EB family member 1) The protein encoded by this gene was first identified by its binding to the APC protein which is often mutated in familial and sporadic forms of colorectal cancer. This protein localizes to microtubules, especially the growing ends, in interphase cells. During mitosis, the protein is associated with the centrosomes and spindle microtubules. The protein also associates with components of the dynactin complex and the intermediate chain of cytoplasmic dynein. Because of these associations, it is thought that this protein is involved in the regulation of microtubule structures and chromosome stability. This gene is a member of the RP/EB family.

The c.455C>A (p.P152H) alteration is located in exon 4 (coding exon 3) of the MAPRE1 gene. This alteration results from a C to A substitution at nucleotide position 455, causing the proline (P) at amino acid position 152 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
