| Invitae | RCV001320815 | SCV001511615 | uncertain significance | Birt-Hogg-Dube syndrome | 2020-10-04 | criteria provided, single submitter | clinical testing | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with FLCN-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces lysine with methionine at codon 78 of the FLCN protein (p.Lys78Met). The lysine residue is moderately conserved and there is a moderate physicochemical difference between lysine and methionine. |
| Ambry Genetics | RCV002447357 | SCV002732377 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-04-20 | criteria provided, single submitter | clinical testing | The p.K78M variant (also known as c.233A>T), located in coding exon 1 of the FLCN gene, results from an A to T substitution at nucleotide position 233. The lysine at codon 78 is replaced by methionine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
