Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000492.4(CFTR):βc.409_412delβ(p.Leu137TyrfsTer15) variant causes a frameshift change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,528 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Pathogenic (β β ). Synonymous variant affecting the same amino acid position (i.e. L137L) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Nov 09, 2023 | This sequence change creates a premature translational stop signal (p.Leu137Tyrfs*15) in the CFTR gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CFTR are known to be pathogenic (PMID: 1695717, 7691345, 9725922). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with cystic fibrosis (PMID: 11379874). This variant is also known as 541 Del CTCC. ClinVar contains an entry for this variant (Variation ID: 53886). For these reasons, this variant has been classified as Pathogenic. - |
