Genes affected

MAP2 (HGNC:6839): (microtubule associated protein 2) This gene encodes a protein that belongs to the microtubule-associated protein family. The proteins of this family are thought to be involved in microtubule assembly, which is an essential step in neurogenesis. The products of similar genes in rat and mouse are neuron-specific cytoskeletal proteins that are enriched in dentrites, implicating a role in determining and stabilizing dentritic shape during neuron development. A number of alternatively spliced variants encoding distinct isoforms have been described. [provided by RefSeq, Jan 2010]

Oct 26, 2022

The c.875T>G (p.M292R) alteration is located in exon 7 (coding exon 4) of the MAP2 gene. This alteration results from a T to G substitution at nucleotide position 875, causing the methionine (M) at amino acid position 292 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
