Susceptibility to tuberculosis is associated with variants in the ASAP1 gene encoding a regulator of dendritic cell migration

Abstract

Human genetic factors predispose to tuberculosis (TB). We studied 7.6 million genetic variants in 5,530 people with pulmonary TB and in 5,607 healthy controls. In the combined analysis of these subjects and the follow-up cohort (15,087 TB patients and controls altogether), we found an association between TB and variants located in introns of the ASAP1 gene on chromosome 8q24 (P = 2.6 × 10−11 for rs4733781; P = 1.0 × 10−10 for rs10956514). Dendritic cells (DCs) showed high ASAP1 expression that was reduced after Mycobacterium tuberculosis infection, and rs10956514 was associated with the level of reduction of ASAP1 expression. The ASAP1 protein is involved in actin and membrane remodeling and has been associated with podosomes. The ASAP1-depleted DCs showed impaired matrix degradation and migration. Therefore, genetically determined excessive reduction of ASAP1 expression in M. tuberculosis–infected DCs may lead to their impaired migration, suggesting a potential mechanism of predisposition to TB.

Supplementary Figure 1 Quality control of the GWAS samples by heterozygosity and missing genotypes rate

Dashed red lines represent QC thresholds of more than 2% missing genotype data or excess ± 3.5 standard deviation of heterozygosity rate. Samples circled in red were excluded from the association study.

Supplementary Figure 2 Principal component analysis (PCA) of the Russian GWAS samples

(a) First and second principal components. Russian samples are plotted with ten HapMap3 populations (ASW – African ancestry in Southwest USA; CEU – Utah residents of European ancestry; CHB – Han Chinese in Beijing, China; CHD – Chinese in Metropolitan Denver, Colorado; JPT – Japanese in Tokyo, Japan; GIH – Gujarati Indians in Houston, Texas; LWK – Luhya in Webuye, Kenya; MKK – Maasai in Kinyawa, Kenya; TSI – Tuscans in Italy; YRI – Yoruba in Ibadan, Nigeria).

(b) All GWAS samples plotted on the first two principal components colored by the city of sample origin.

(c) Russian TB cases and controls projected onto the first two principal components using SNP weights precomputed from European samples in the 1000 Genomes Phase III project (CEU — Utah residents with Northern and Western European ancestry; IBS — Iberian populations in Spain; FIN — Finnish in Finland; GBR — British in England and Scotland; and TSI — Toscani in Italy) using SNPweights (Chen, C.Y. et al. Improved ancestry inference using weights from external reference panels. Bioinformatics 29, 1399-1406 (2013)).

Supplementary Figure 3 The quantile - quantile plot of the observed versus the expected –log10P-values under the null for 7,614,862 SNPs from the GWAS results after genotype imputation

The diagonal black line is y = x, and the grey shapes show 95% confidence interval under the null. The overall distribution has a genomic inflation factor (λGC) of 1.10.
