As an example, of the SNPs suggestively associated with BPD in GWAS, those within RASGFR1 (encoding Ras protein specific guanine nucleotide releasing factor 1) may represent real associations, since other SNPs located near this gene showed association signals in a previous GWAS of BPD11. The gene discussed is RASGRF1; the disease is bronchopulmonary dysplasia.
