Family-based Study on Ulcerative Colitis with Whole Exome Sequencing. Family-based Study on Ulcerative Colitis with Whole Exome Sequencing

Genetic risk factors for ulcerative colitis are not well understood. We performed a family-based whole exome sequencing analysis to identify potential causal mutations. In the proband, we found a heterozygous de novo mutation in the gene HSPA1L. Our results indicate that the de novo mutation in HSPA1L is associated with ulcerative colitis.
