GeneDx RCV000082634 SCV000321652 pathogenic not provided 2015-11-03 criteria provided, single submitter clinical testing The c.296delA pathogenic variant in the FLCN gene has been reported previously in association with Birt-Hogg-Dube syndrome (Schmidt et al., 2005; Toro et al., 2008). The deletion causes a frameshift starting with codon Aspartic Acid 99, changes this amino acid to a Valine residue, and creates a premature Stop codon at position 31 of the new reading frame, denoted p.Asp99ValfsX31. This pathogenic variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay.

Invitae RCV000239648 SCV000940601 pathogenic Multiple fibrofolliculomas 2019-11-20 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Asp99Valfs*31) 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 observed in individuals affected with Birt-Hogg-Dub syndrome (PMID: 15852235, 18234728). This variant is also known as c.751delA in the literature. ClinVar contains an entry for this variant (Variation ID: 96482). Loss-of-function variants in FLCN are known to be pathogenic (PMID: 15852235). For these reasons, this variant has been classified as Pathogenic.
