The CFTR c.4056G>T; p.Gln1352His variant (rs113857788), and another variant resulting in the same amino acid change (c.4056G>C; p.Gln1352His), are reported in the literature in multiple individuals affected with CFTR-related disorders such as pancreatitis and congenital bilateral absence of the vas deferens (Anzai 2003, Claustres 2017, Lee 2003, Ratbi 2007). The p.Gln1352His variant is also reported to be enriched in Asian pancreatitis patients compared to unaffected individuals (Claustres 2005, Kondo 2015, Nakano 2015). Expression of the variant protein in a cell line reveals a significant reduction in mature CFTR protein detected compared to wildtype (Lee 2003). The c.4056G>T; p.Gln1352His variant is reported in ClinVar (Variation ID: 35882), and is found in the general population with an overall allele frequency of 0.006% (17/282620 alleles) in the Genome Aggregation Database. The glutamine at residue 1352 is highly conserved and computational algorithms (PolyPhen-2, SIFT) predict that the variant is deleterious. Based on available information, this variant is considered to be mildly pathogenic. References: Anzai C et al.
