Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000492.4(CFTR):c.3002_3003del(p.Val1001AspfsTer45) variant causes a frameshift change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,058 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Pathogenic (★★★). Synonymous variant affecting the same amino acid position (i.e. I1000I) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 10, 2014 | The c.3002_3003delTG pathogenic mutation (also known as 3132delTG), located in coding exon 19 of the CFTR gene, results from a deletion of two nucleotides between nucleotide positions 3002 and 3003, causing a translational frameshift with a predicted alternate stop codon (V1001Dfs*45). This pathogenic mutation was first identified in two individuals with cystic fibrosis and pancreatic insufficiency (PI); one individual also carried deltaF508 and the other did not have a second mutation identified (Bonizzato A et al. Hum Genet. 1995;95(4):397-402). In addition to the clinical data available in the literature, since frameshifts are typically deleterious in nature, this alteration is interpreted as a disease-causing mutation (ACMG Recommendations for Standards for Interpretation and Reporting of Sequence Variations. Revision 2007. Genet Med. 2008;10:294). - |
