The functional variant of the 5-HT1A receptor thus influences the response of schizophrenia patients to atypical antipsychotics and may be useful in the future to predict the pharmacogenetics of negative symptoms.

Positron emission tomography (PET) imaging of the 5-HT(1A) receptor in patients with Alzheimer's disease, schizophrenia and depression implicate an alteration in 5-HT(1A) receptor binding compared to control subjects, but it is yet unknown whether these alterations are related to the cognitive impairment associated with these disorders.

Using a metabolic pathway approach, it can be shown that the best current candidate gene locus for a subtype of schizophrenia located on chromosome 5q11-13 (HGML10 # SCZD1 and OMIM #181510) is in the serotonergic pathway, i.e. a receptor for 5-hydroxytryptamine (subtype 1A; HGML10 #HTR1A) which also maps in the same chromosomal region.5.
