---|---|---|
(A;A) | 2.6 | introversion; depression resistant; impaired motor skills learning; somewhat quicker mental decline in Alzheimer patients |
(A;G) | 2.6 | Slightly increased risk for ADHD or depression; somewhat quicker mental decline in Alzheimer patients |
(G;G) | 0 | common/normal |
Met/Met (higher risk) variant of the Val66Met SNP in the BDNF gene that codes for brain-derived neurotrophic factor. Met/Met is associated in some (but not all) studies with slightly increased susceptibility to certain mental health disorders such as ADHD and depression.

This genotype may provide resistance to depression when subjected to repeated defeat blog summary
On a driving-based motor learning task subjects with this genotype showed greater error during short-term learning and poorer retention over 4 days, relative to subjects without the polymorphism. The presence of this BDNF polymorphism is associated with differences in brain motor system function, altered short-term plasticity, and greater error in short-term motor learning. [PMID 19745020]
