Findings

This intronic variant in MAPT is thought to be a relatively rare polymorphism and does not appear to be associated with disease. In one study it was found in one out of 117 controls and zero out of 101 people affected by early onset Alzheimer's disease (Roks et al., 1999). It was later found in two out of 72 AD patients and zero out of 58 controls (Frigerio et al., 2015).

Neuropathology

Not applicable.

Biological Effect

This intronic point mutation does not appear to alter the splicing of exon 10 (D'Souza et al., 1999).
