This variant is reported as pathogenic in ClinVar (Variation ID: 7231), and found in the general Latino population with an allele frequency of 0.009% (3/33540 alleles) in the Genome Aggregation Database. This variant causes a frameshift by deleting a single nucleotide, so it is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, this variant is considered to be severely pathogenic. REFERENCES CFTR2 database: https://cftr2.org/ Sosnay PR et al.
