This study analyzed the association between the genetic profile of patients with diabetic macular edema (DME) and their response to intravitreal anti-VEGF injection. Several genes were found to be associated with treatment response, including DIRC3, SLCO3A1, and RAB2A. Pathway analysis revealed a connection between RAB2A and CREB5 with AMPK signaling related to VEGF. These genetic biomarkers can provide insights into patient response and guide therapeutic strategies.
Diabetic macular edema (DME), a complication of diabetes mellitus, is a leading cause of adult-onset blindness worldwide. Recently, intravitreal anti-VEGF injection has been used as a first-line treatment. This study analyzed the association between the genetic profile of patients with DME and their response to treatment. Intravitreal anti-VEGF injections were administered monthly for three months to Korean patients diagnosed with DME, who were classified into two groups depending on whether they responded to anti-VEGF therapy or showed recurrence within six months. Peripheral blood samples were used for genetic analyses. Genome-wide association analysis results sowed that the genes DIRC3 on chromosome 2 (rs16857280, p=1.2x10(-6)), SLCO3A1 on chromosome 15 (rs12899055, p=2.5x10(-6)), and RAB2A on chromosome 8 (rs2272620, p=4.6x10(-6)) were associated with treatment response to intravitreal anti-VEGF injection. SLC35F1, TMEM132D, KIAA0368, HPCAL1, IGF2BP3, SPN2S, COL23A1, and CREB5 were also related to treatment response (p<5.0x10(-5)). Using the KEGG pathway analysis, RAB2A and CREB5 were found to be associated with AMPK signaling related to VEGF (p=0.018). The identified genetic biomarkers can elucidate the factors affecting patient response to intravitreal anti-VEGF injection and help select appropriate therapeutic strategy.
