It is reported as a variant of uncertain significance in ClinVar (Variation ID: 35840) and observed in the Latino population at an overall frequency of 0.09% (19/21632 alleles) in the Genome Aggregation Database. The arginine at codon 792 is highly conserved and computational algorithms (SIFT, PolyPhen-2) predict that this variant is deleterious. In vitro functional studies of the variant protein demonstrate reduced chloride current and disruption of a consensus recognition site used for CFTR activation (Vankeerberghen 1998). However, due to limited clinical information regarding this variant, its clinical significance cannot be determined with certainty. References: Ravnik-Glavac M et al.
