Invitae RCV001203130 SCV001374277 uncertain significance Autosomal dominant Parkinson disease 8 2022-07-12 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 778 of the LRRK2 protein (p.Ser778Asn). 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"). ClinVar contains an entry for this variant (Variation ID: 934690). This variant has not been reported in the literature in individuals affected with LRRK2-related conditions. This variant is not present in population databases (gnomAD no frequency).

Ambry Genetics RCV003163532 SCV003855616 uncertain significance Inborn genetic diseases 2023-02-23 criteria provided, single submitter clinical testing The p.S778N variant (also known as c.2333G>A), located in coding exon 19 of the LRRK2 gene, results from a G to A substitution at nucleotide position 2333. The serine at codon 778 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is conserved. 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.
