| 613003 | OMIM | Attention deficit-hyperactivity disorder 7 (ADHD7) | A neurobehavioral developmental disorder primarily characterized by the coexistence of attentional problems and hyperactivity, with each behavior occurring infrequently alone. Disease susceptibility is associated with variants affecting the gene represented in this entry. Naturally occurring variants of TPH2 with impaired enzyme activity could cause deficiency of serotonin production and result in an increased risk of developing behavioral disorders. |
