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.

LRRK2-DT (HGNC:40848): (LRRK2 divergent transcript)

ACMG classification

Our verdict: Likely_benign. The variant received -5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.7).
• BP6: Variant 12-40225164-G-A is Benign according to our data. Variant chr12-40225164-G-A is described in ClinVar as Likely_benign. ClinVar VariationId is 1731039.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=0.921 with no splicing effect.
