SNP rs28416813 is located within the 5′UTR of IFNL3 and might be functionally relevant for transcriptional regulation of IFNL3. Functional significance of rs688187, located downstream of IFNL3, is unknown, but this SNP was reported to be associated with mucinous ovarian carcinoma in a GWAS (Kelemen and others 2015), likely as a proxy for other variants in this LD block. Here, IFNL3 is linked to ovarian mucinous adenocarcinoma.
