140 R4590W was discovered in a control and in the test stage was relatively frequent and found in 17 cases and 4 controls. Login to comment
173 Two bipolar cases were compound heterozygotes carrying both the H3609P and R4590W mutations, one bipolar case carried H3609P and T4550A, and one person with severe chronic schizophrenia was homozygous for H3609P. Login to comment
197 A second type of variant (mostly missense mutations), have higher frequencies of up to 2%-3% in the case population, ORs of 2 or more, and tend to show less familial aggregation.82 In the present study S3704R conforms to the first class of null private mutation with high penetrance and low frequency whereas the missense mutations H3609P, T4550A, and R4590W show characteristics more typical of the second class by virtue of also being detected in controls, having moderate ORs, and higher observed frequencies.
