• rs896174811
• NM_003980.6:c.1595G>C

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_003980.6(MAP7):​c.1595G>C​(p.Arg532Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R532C) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 33)
• Consequence: MAP7 NM_003980.6 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 2.14

Genes affected

MAP7 (HGNC:6869): (microtubule associated protein 7) The product of this gene is a microtubule-associated protein that is predominantly expressed in cells of epithelial origin. Microtubule-associated proteins are thought to be involved in microtubule dynamics, which is essential for cell polarization and differentiation. This protein has been shown to be able to stabilize microtubules, and may serve to modulate microtubule functions. Studies of the related mouse protein also suggested an essential role in microtubule function required for spermatogenesis. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2010]
