Abstract | The neurotransmitter disturbances responsible for cognitive dysfunction in schizophrenia are hypothesized to originate with alterations in postsynaptic scaffold proteins. We have recently reported that protein levels of FRMPD4, a multiscaffolding protein that modulates both Homer1 and postsynaptic density protein 95 activity, is altered in the schizophrenia postmortem brain, in regions involved in cognition. Here, we set out to investigate whether genetic variation in FRMPD4 is associated with cognitive function in people with schizophrenia. We selected and examined a novel single nucleotide polymorphism, rs5979717 (positioned in the noncoding 3′ untranslated region of FRMPD4 and potentially influencing protein expression), for its association with schizophrenia and nine measures of cognitive function, using age-matched and sex-matched samples from 268 schizophrenia cases and 268 healthy controls. Brain samples from 20 schizophrenia patients and 20 healthy controls were additionally genotyped to study the influence of this variant on protein expression of FRMPD4. Allelic distribution of rs5979717 was associated with schizophrenia in females (χ2=4.52, P=0.030). No effects of rs5979717 were observed on cognitive performance, nor an influence of rs5979717 genotypes on the expression of FRMPD4 proteins in postmortem brain samples. These data provide initial support for a sex-specific role for common variation in rs5979717 in schizophrenia, which now warrants further investigation. |
