MAPT

Alias

DDPAC; FTDP-17; MAPTL; MSTD; MTBT1; MTBT2; PPND; PPP1R103; TAU

Associated disorders

The MAPT gene is associated with a spectrum of related autosomal dominant neurodegenerative disorders including frontotemporal dementia (FTD) (MedGen UID: 83266), Pick disease (MedGen UID: 116020), and progressive supranuclear palsy 1 (PSNP1) (MedGen UID: 21026), collectively known as MAPT-related tauopathies. Additionally, the MAPT gene has preliminary evidence supporting a correlation with susceptibility to late-onset Parkinson’s disease (MedGen UID: 463618) and with autosomal recessive Parkinson-dementia syndrome (MedGen UID: 337962; PMID: 11220749, 14991829).

Invitae tests that include this gene:

The MAPT gene encodes microtubule associated protein tau. Tau is involved in the formation of the cytoskeletal framework of neurons by promoting microtubule polymerization and stabilization.

Assay and technical information

Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).

Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence, and select noncoding variants. Our assay provides a Q30 quality-adjusted mean coverage depth of 350x (50x minimum, or supplemented with additional analysis). Variants classified as pathogenic or likely pathogenic are confirmed with orthogonal methods, except individual variants that have high quality scores and previously validated in at least ten unrelated samples.

Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
