Genes affected

MAP6 (HGNC:6868): (microtubule associated protein 6) This gene encodes a microtubule-associated protein. The encoded protein is a calmodulin-binding and calmodulin-regulated protein that is involved in microtubule stabilization. Two transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

The c.668G>A (p.G223D) alteration is located in exon 1 (coding exon 1) of the MAP6 gene. This alteration results from a G to A substitution at nucleotide position 668, causing the glycine (G) at amino acid position 223 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
