AA= Short Allele 91% of the time. AG= long 96% of the time.

Based on with 2823 samples a haplotype of T+A in rs2129785 (T) +rs11867581 (A) predicts short allele with good accuracy [R]

The A (minor) allele is associated with:

  • Short allele= lower transporter, higher 5HT.
  • better response to bright light.

The G (major) allele is associated with:


Parent Gene: SERT, SLC6A4

Importance: 5
Less common allele: A = 48%
More common allele: G = 52%
