Inflammatory bowel disease
Gene: HSPA1L
PMID:28126021 reported the identification of a heterozygous de novo variant (p.Ser277Leu) in HSPA1L in a patient with inflammatory bowel disease. In addition, five additional rare HSPA1L variants (p.Gly77Ser, p.Leu172del, p.Thr267Ile, p.Ala268Thr, p.Glu558Asp) were identified in six patients from a cohort of 136 IBD patients with WES data. Functional studies showed that all six HSPA1L variant proteins showed decreased chaperone activity in vitro. Moreover, three variants demonstrated dominant negative effects on HSPA1L and HSPA1A protein activity.
However, the variants identified are present at relatively high frequencies in gnomad V4, in particular p.Thr267Ile is present in 281 individuals, and the p.Ala268Thr is present in 4,753 individuals.
