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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.2002C>A (p.P668T) alteration is located in exon 4 (coding exon 4) of the MAP6 gene. This alteration results from a C to A substitution at nucleotide position 2002, causing the proline (P) at amino acid position 668 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
