Ambry Genetics RCV003310474 SCV004001665 uncertain significance Inborn genetic diseases 2023-04-30 criteria provided, single submitter clinical testing The p.N1068S variant (also known as c.3203A>G), located in coding exon 24 of the LRRK2 gene, results from an A to G substitution at nucleotide position 3203. The asparagine at codon 1068 is replaced by serine, 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.
Labcorp Genetics (formerly Invitae), Labcorp RCV005102694 SCV005830335 uncertain significance Autosomal dominant Parkinson disease 8 2024-10-09 criteria provided, single submitter clinical testing This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 1068 of the LRRK2 protein (p.Asn1068Ser). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with LRRK2-related conditions. ClinVar contains an entry for this variant (Variation ID: 2562414). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on LRRK2 protein function. 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.
