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]

The c.1780G>T (p.A594S) alteration is located in exon 12 (coding exon 12) of the MAP7 gene. This alteration results from a G to T substitution at nucleotide position 1780, causing the alanine (A) at amino acid position 594 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
