Genes affected

LRRK2 (HGNC:18618): (leucine rich repeat kinase 2) This gene is a member of the leucine-rich repeat kinase family and encodes a protein with an ankryin repeat region, a leucine-rich repeat (LRR) domain, a kinase domain, a DFG-like motif, a RAS domain, a GTPase domain, a MLK-like domain, and a WD40 domain. The protein is present largely in the cytoplasm but also associates with the mitochondrial outer membrane. Mutations in this gene have been associated with Parkinson disease-8.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM1

In a modified_residue Phosphoserine (size 0) in uniprot entity LRRK2_HUMAN

BP4

Computational evidence support a benign effect (MetaRNN=0.24432394).

BS2

High AC in GnomAdExome4 at 6 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 973 of the LRRK2 protein (p.Ser973Asn). This variant is present in population databases (rs75148313, gnomAD 0.0009%). This missense change has been observed in individual(s) with Parkinson disease (PMID: 17523199, 21885347). ClinVar contains an entry for this variant (Variation ID: 39158). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt LRRK2 protein function. Experimental studies have shown that this missense change does not substantially affect LRRK2 function (PMID: 20642453, 35950872). 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. -
