We genotyped the samples from the validation set for the above six SNPs, which either showed nominally significant associations (p < 0.05) with risk of SSc overall (LRRC34 rs6793295 and OBFC1 rs11191865) or with SSc-ILD (rs7934606 in MUC2) and FVC% predicted (DSP rs2076295, SPPL2C rs17690703 and MAPT rs1981997). This evidence concerns the gene LRRC34 and interstitial lung disease.
