Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PVS1PP5_Moderate
The NM_144997.7(FLCN):c.997_998del(p.Ser333ArgfsTer56) variant causes a frameshift change involving the alteration of a non-conserved nucleotide. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. S333S) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Genes affected
FLCN (HGNC:27310): (folliculin) This gene is located within the Smith-Magenis syndrome region on chromosome 17. Mutations in this gene are associated with Birt-Hogg-Dube syndrome, which is characterized by fibrofolliculomas, renal tumors, lung cysts, and pneumothorax. Alternative splicing of this gene results in two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

Birt-Hogg-Dube syndrome Pathogenic:2
Pathogenic, no assertion criteria provided | clinical testing | Division of Respiratory Medicine of Juntendo University, Juntendo University Faculty of Medicine and Graduate School of Medicine | Jul 01, 2023 | - - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 24, 2017 | For these reasons, this variant has been classified as Pathogenic. This sequence change creates a premature translational stop signal (p.Ser333Argfs*56) in the FLCN gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been reported in an individual with symptoms consistent with Birt–Hogg–Dub_x0001_é syndrome (PMID: 24393238). Loss-of-function variants in FLCN are known to be pathogenic (PMID: 15852235). - |
