This variant is considered to cause severe cystic fibrosis when identified with another severe pathogenic variant on the opposite chromosomes. CFTR2 database: Sosnay PR et al.

Quest Diagnostics Nichols Institute San Juan Capistrano RCV000224705 SCV000889287 pathogenic not provided 2018-09-13 criteria provided, single submitter clinical testing The best available variant frequency is uninformative. Found in at least one symptomatic patient. Occurs in multiple cases with a recessive pathogenic variant in the same gene. Assessment of experimental evidence suggests this variant results in abnormal protein function.
Integrated Genetics/Laboratory Corporation of America RCV000780118 SCV000917162 pathogenic not specified 2017-10-30 criteria provided, single submitter clinical testing Variant summary: The CFTR c.1519_1521delATC (p.Ile507del) variant involves the deletion of three nucleotides, leading to an in-frame deletion of a isoleucine residue in the ABC transporter-like and AAA+ ATPase domains (InterPro). One in silico tool predicts a damaging outcome for this variant. This variant was found in 10/276978 control chromosomes at a frequency of 0.0000361, which does not exceed the estimated maximal expected allele frequency of a pathogenic CFTR variant (0.0129603). The variant has been identified in many CF patients and is considered a common variant, as it was found in 1.6% of CF alleles in a large, nationwide retrospective study (McKone_2003). Patients with this variant have a mean chloride conductance of 0.2% as of the WT CFTR (Sosnay_2013). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is classified as pathogenic.
