Invitae | RCV000553493 | SCV000625723 | pathogenic | Cystic fibrosis | 2017-10-04 | criteria provided, single submitter | clinical testing | This variant is an in-frame deletion of the genomic region encompassing exons 25-26 of the CFTR gene. It preserves the integrity of the reading frame. Deletions of exons 25-26 been reported in individuals affected with cystic fibrosis (PMID: 15024729, 16362824, 18683213). Due to alternative exon nomenclature, this variant is also known as deletion of exons 22-23 in the literature. This deletion disrupts the nucleotide binding domain (NBD2) of the CFTR protein, which is essential for ATP hydrolysis and proper CFTR function (PMID: 15284228). For these reasons, this variant has been classified as Pathogenic. |
