Genes affected

CFTR (HGNC:1884): (CF transmembrane conductance regulator) This gene encodes a member of the ATP-binding cassette (ABC) transporter superfamily. The encoded protein functions as a chloride channel, making it unique among members of this protein family, and controls ion and water secretion and absorption in epithelial tissues. Channel activation is mediated by cycles of regulatory domain phosphorylation, ATP-binding by the nucleotide-binding domains, and ATP hydrolysis. Mutations in this gene cause cystic fibrosis, the most common lethal genetic disorder in populations of Northern European descent. The most frequently occurring mutation in cystic fibrosis, DeltaF508, results in impaired folding and trafficking of the encoded protein. Multiple pseudogenes have been identified in the human genome. [provided by RefSeq, Aug 2017]

Collection Method:clinical testing

This sequence change replaces glutamine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 1411 of the CFTR protein (p.Gln1411Pro). This variant is present in population databases (rs150177304, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with CFTR-related conditions. ClinVar contains an entry for this variant (Variation ID: 495947). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Q1411P variant (also known as c.4232A>C), located in coding exon 26 of the CFTR gene, results from an A to C substitution at nucleotide position 4232. The glutamine at codon 1411 is replaced by proline, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: The c.4232A>C (p.Gln1411Pro) in CFTR gene is a missense change that involves a mildly conserved nucleotide and 5/5 in silico tools predict deleterious outcome. The variant of interest is located within AAA+ ATPase domain functional domain and several neighboring variants have been associated with CF, although the functional impact of this missense change is yet to be studied. The variant is present in the large control population dataset of ExAC at a frequency 0.0000166 (2/120320 chrs tested), exclusively in individuals of Latino descent (0.00017; 2/11398) which does not exceed the maximal expected frequency of a pathogenic allele (0.013) in this gene. This variant was identified in a population screening of patients with primary sclerosing cholangitis and inflammatory bowel syndromes (Sickkids db). The variant has not, to our knowledge, been reported in affected individual via published reports or classified by a reputable database/clinical laboratory. At this time there is not sufficient undeniable evidence to classify this variant with confidence. Taken together, the variant was classified as VUS until more data becomes available. -
