Invitae RCV001222305 SCV001394399 uncertain significance Birt-Hogg-Dube syndrome 2019-04-30 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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with FLCN-related conditions. This variant is present in population databases (rs184718358, ExAC 0.01%). This sequence change replaces proline with serine at codon 359 of the FLCN protein (p.Pro359Ser). The proline residue is weakly conserved and there is a moderate physicochemical difference between proline and serine.
Ambry Genetics RCV003163719 SCV003860940 uncertain significance Hereditary cancer-predisposing syndrome 2022-11-30 criteria provided, single submitter clinical testing The p.P359S variant (also known as c.1075C>T), located in coding exon 7 of the FLCN gene, results from a C to T substitution at nucleotide position 1075. The proline at codon 359 is replaced by serine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
