Detail Info
| Sample Diagnosis |
DSM-IV-TR criteria |
| Sample Status |
Exclusion criteria included other axis I disorders, as well as neurological illness, organic mental disorders and chronic immune or inflammatory disorders. |
| Technique |
PCR |
| Statistical Method |
Allelic and genotypic associations were done using X2 tests with respect to diagnostic subgroups. |
| Result Summary |
No genotypic or allelic association for the A-2518G polymorphism of SCYA2 was found considering cases and controls. Nevertheless, when comparisons were run between MDD versus BD patients (any subtype), a significantly higher frequency of the AA genotype and of the A allele was observed in subjects with BD. In addition, independently from diagnosis, a higher number of lifetime suicide attempts was found in subjects with the AA genotype of the A-2518G polymorphism of the MCP-1 gene. |

Across all groups (controls, MDD, BD I, BD II): genotype: X2=8.215, d.f. = 6, P-value = 0.223; allele: X2 = 5.058, d.f. = 3, P-value = 0.168. Across patient groups (controls, cases): genotype: X2 = 8.140, d.f. = 4, P-value = 0.087; allele: X2 = 5.044, d.f. = 2, P-value = 0.080. MDD versus BD patients: genotype: X2 = 7.233, d.f. = 2, P-value = 0.027; allele: X2 = 4.730, d.f. = 1, P-value = 0.030.

The present preliminary results, though limited by the relatively small sample, suggest a possible role of the SCYA2 in conferring susceptibility to BD.
