Supplementary Fig1. The sequence rare variants of ATG5 identified in 8 patients and one healthy control.

a A presents the 5 rare variants of ATG5 only identified in one lupus nephritis patient respectively. B presents the rare variant of ATG5 identified in one lupus nephritis patient and one healthy control. C presents the two rare variants of ATG5 only identified in one systemic lupus erythematosus patient without renal damage respectively.

b All the variants are marked with arrows.

a Abbreviations: LN=lupus nephritis, MAF=Minor allele frequency.

b P values were calculated by chi-square test using 2 × 2 contingency tables based on allele frequencies.

c None of the genotypes in the controls showed significant deviation from Hardy-Weinberg equilibrium.

d Chromosome positions were according to the National Center for Biotechnology Information reference assembly.
