Genes affected

LRRK1 (HGNC:18608): (leucine rich repeat kinase 1) This gene encodes a multi-domain protein that is a leucine-rich repeat kinase and a GDP/GTP binding protein. The encoded protein is thought to play a role in the regulation of bone mass. Mice lacking a similar gene showed severe osteopetrosis, increased bone mineralization and decreased bone resorption.

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_024652.6.

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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals affected with LRRK1-related conditions. This variant is not present in population databases (gnomAD no frequency). This variant, c.14_34del, results in the deletion of 7 amino acid(s) of the LRRK1 protein (p.Ser5_Met11del), but otherwise preserves the integrity of the reading frame. -
