Neuroticism is a personality trait. It is measured with the NEO family of personality tests.

It is related to the harm avoidance trait from the Cloninger personality questionnaires.

In NEO PI-R neuroticism has the following subtraits:

  1. Anxiety (N1)
  2. Angry hostility (N2)
  3. Depression (N3)
  4. Self-consciousness (N4)
  5. Impulsiveness (N5)
  6. Vulnerability to stress/Vulnerability (N6)

A genome-wide association study among 6148 individuals pointed to rs18497010 in TMEM16D and rs362584 in SNAP25 (among others) as associated with neuroticism though neither of these showed any particular association in replication.[1]
